After the chroning all weapons get a colored cable tie according to gun’s power.
  • High Power Air-gun adjustment valves will be sealed after chroning. Players must bring their own seals. If the seal is removed or lost, player must get new one and bring their weapon for chroning again.


  • When you get hit, shout Hit loud and clearly and/or act accordingly. Take out your big orange deathrag and place it so others can see it!
  • In the dark you should also use a red glowing stick or a red light in addition with your deathrag. It would be smart to also shout “dead player” once in a while so that others know you are offgame. You are not obligated to mark yourself with a red light when wounded.
  • Clear ricochets from houses or vehicles do not count as hits
  • Hits to the players weapon disable it. Vehicle turret is not affected by bb hits. Fix your gun by visiting the main base or respawn point.

  • Sneak up to your target, touch his body and say “Knife Kill“.
  • A knifed-killed person moans quietly for a moment and then lies dead still for 10 minutes.

Knock out​

  • Knock out is a good option to handle a person that you don’t want to eliminate.
  • Sneak up behind your target, touch his head and say Knock out.
  • The target falls to the ground quietly and stays still for 5 minutes.
  • After this, the target wakes up but does not remember anything from the last 5 minutes.
  • Players wearing helmets cannot be knocked out.


  • A wounded player has 10 minutes to be healed before the player bleeds out. You are not allowed to try avoid get being looted by bleeding out sooner.
  • A wounded player can be knife killed with your hand. Shooting a wounded player on purpose is not allowed.
  • The wounded player can call ”Medic” or ”Lääkintämies” shouting or by radio, but can’t communicate about what happens around him.
  • Wounded player can be moved if aided by another player. Neither helper nor the wounded can use their weapons or heal the wounded at that time. When moving other player, you both must larp a little bit. Running with your helper with just holding hands is not enough.

Healing and medics

  • Player can be healed by friendly or enemy medics or civilian doctors.
  • Medics are allowed to carry a maximum of 10 white field dressings at once. Field dressings can be restocked by visiting the main base or respawn point. Players can bring their own white field dressings but they are also sold by game masters.
  • Healing a wounded player takes 2 minutes. Medic can’t use weapons during healing unless he stops. After this the healing must be started again from beginning.
  • The player can be healed only once, unless the faction has achieved special permission. Information about such permissions will be available from the HQ and possibly in the -website.

Mobile Field Hospital Vehicle

Operating times

  • After deploying the Mobile field hospital, the Mobile field hospital can operate for 1 hour.
  • After 1 hour it cannot be used again for 2 hours.
  • When deploying the Mobile field hospital, the engine must be off and it cannot be moved for 1 hour. If deployed vehicle is moved you cannot use it as respawn for 2 hours.


  • To heal injured troops you must assing a medic to be present at the vehicle.
  • You can heal max. 5 players at the same time (=remove their bandages).
  • Healing (removing bandage) takes 10 minutes for every player. When being healed, players cannot use their weapons. If healing is stopped the countdown resets.
  • Medics can replenish their bandages at the vehicle.

Other rules

  • If the medic at the vehicle is shot, you cannot use the Mobile hospital until the same medic is alive again.
  • The vehicle can be destroyed by the enemy. In case the vehicle is destroyed regular vehicle rules, such as respawn times, do apply.
  • The vehicle or the assigned medic can be changed at base/when respawning.
  • Only unarmed LVL1 vehicles can act as Mobile field hospital and there is only one per faction. The vehicle must have Ehasa provided “MOBILE FIELD HOSPITAL” markings on both sides.


Capture- and resource points

Rallypoint cache

  • You can recognize rallypoint from small one man tent or tarp, colored tape around a respawn area and the faction flag on the tent/tarp.
  • Rallypoints are exhausted when used. Inside the tent there is a board where you must mark every respawn you make. Respawning happens half hour intervals at xx:00 and xx:30 (e.g. 13:00 or 14:30).
  • Rallypoints are respawn points which can be set up anywhere in the game area.
  • Faction can obtain more resourceboards by completing missions or stealing them.
  • Faction can move their own rallypoints whenever they wish. Inform your superiors about moving the rallypoint so the information reaches faction leaders.
  • You can disable an enemy cache by stealing the resource tables. The enemy’s rallypoint cache nevertheless remains part of the game. Stolen boards can be used to operate your own cache.

Less leathal weapons

  • You can use so called less leathal weapons in game that do not kill the player. These are provided by the game masters.
    1. Training OC-spray, which deploys water or soap water.
    2. Tasers, which are colored waterpistols.
    3. Batons, which are either made from plastic, foam or soft rubber(suitable for training-use).
  • Both taser and oc-spray are used by shooting a short spray at the enemys torso, not the face. Baton is used by touching softly the enemy in the arm or leg.
  • Using these methods may be wise for stopping ongoing larp fights with less lethal force.
  • When the player is sparayed, tazed or hit with a baton he is unconcious for 5 minutes.
  • The player can be taken prisoner after being sprayed, after which have will turn from being unconcious to captive. 

Ingame money

  • There will be ingame money which is mainly used by civilians but regular players might get their hands on it in certain missions.
  • Using other than money provided by the game masters is forbidden and might lead to a ban from the game.

Searching a player

Player can be searched for any ingame items. Before starting the search, the player should be informed about the search. The search must then be carried out while respecting sensitive areas of the body.

If the player does not want to be searched, he/she must say it outloud and hand over all in-game material in his/her possession.

Any ingame material found in the search can be taken away from the player. During the search the player must tell the searcher when they are handling in-game material.


  • You are allowed to take prisoners.
  • Consent is reguired from the prisoner. If consent is not given or it’s withdrawn the prisoner is required to hand out all ingame material and go to respawn area for respawning.
  • If a player is taken as a prisoner, his weapon can be confiscated if he’s fine with it. If the player grabs the weapon back, he can use it. Another option is to wrap colored tape (ex. red) around the barrel to mark the weapon as confiscated.
  • If a prisoner escapes/is released, he can use his taped weapon’s after 5 minutes.
  • Imprisoned player can only knife kill with a hidden knife not found in strip search. The knife must be a soft replica and suitable for knife kills. You can however still use knock out.
  • Prisoners weapons cannot be used by other players.
  • A captured player can be “tied up” with a painters tape or cable tie that lacks the locking tongue. The tape / cable tie can be used only with the player’s own permission and the hands must be “tied” to the front. The player must be able to remove the tape/cable tie by himself.
  • Main factions can capture and deliver the civilians to a “Brigade-jail” by bringing the civililian to the factions base. By doing this the faction can remove temporarily a game character. The use of the “Brigade-jail” must always be informed to game masters – preferably in advance.

Locked rooms/spaces

  • There might be doors/objectives which are covered with a tarp or a door and a note stating that it is a locked door/objective. These doors/objectives are locked and cannot opened without an ingame key.
  • These doors/objectives can be broken/blown up by props which are handed out by the game masters. Breaking the door can be done by an “Engineer”. Blowing up must be done in supervision of a game master and before the explosion you must shout Fire in the hole.
  • It is forbidden to shoot into or from a locked room.



  • Engineers are the only ones who can set up and disable AT-mines, open rooms with explosives or fix destroyed in game vehicles.
  • There can only be 1 engineer per group and he must wear an engineer -path (sold at check-in) visible at all times. Civilian players can also be engineers.


  • The factions may have the ability to use a limited amount of artillery.
  • Artillery is ordered through the chain of command. By request, the game masters use pyrotechnics(He-shells), smokes(Smoke-shells) and other means to describe the artillery. Eventual need of ear protection will be indicated in advance by game masters.
  • Game masters point out those wounded by the artillery as well as when it begins and ends. Artillery hit on a vehicle counts as one projectile hit. One artillery strike effects in approx 50 m x 50 m area.

Grenades and pyrotechnics

  • Players are not allowed to bring their own smoke or BB grenades or pyrotechnics.
  • The reason for the ban is that the high volume of waste produced by grenades affecting the process of getting game areas.


  • There will be ingame and offgame vehicles. You need to be extra careful when near vehicles. Enemy vehicle doors cannot be opened to prevent accidents.
  • Players must register their vehicle in advance at the kuulaportti-service. Vehicles are assigned max a three-digit number that indicates the identification numbers of the vehicle. Vehicle category will be determined based on vehicles equipment. Final marking in vehicle will be example 1-1, 2-10, 1-100 etc. At the same time, the category describes how many hits the vehicle can take. The same identification number remains same in all Ehasa ry events, making it easier for us to monitor the use of vehicles. The final decision on the vehicle category will be made on game area in the separate vehicle registration and chronoing process. Information will be available in the website.
  • Max. speed for vehicles is 20km/h. The game masters will use common sense and caution to avoid accidents when driving, still not driving faster than 60km/h that is restricted by the law. Everyone should pay extraordinary caution when driving.
  • In principle, game masters will not transport players during the game, except emergencies, helicopter transports and at the end of the game any drivers back to the parking area.
  • Some of the in game vehicles have a blocked field of view and the movement of such vehicles might also be hard or sudden. For this reason it is forbidden to go near a vehicle when its engine is running, unless the vehicle crew instructs you otherwise.
  • If you want to shoot from the windows, they must be fully opened and taped to stay in place. This must be done before leaving main base and you cannot do it in field. Windows may be kept a little open for safety reasons. In this case it is not allowed to shoot out of this gap and the passangers can ignore any bb’s coming in through the gap!
  • The transportation of personnel on trailers is prohibited.
  • If you have a problem, you can leave feedback to the game masters using the form on .

  • In addition, the factions may have access to limited waterborne transport which allows them to transfer a certain number of players by water in the area of Lake Iso-Tarus.
  • Players are transported by the game masters and the players own vehicles or boats with offgame markings to the drop zone. If the transport vehicles are only the players own vehicles, the vehicles must have a separate “skill card” provided by the game masters, which indicates that it is an offgame transport.
  • Players are back ingame, when they disembark the vehicle. The players who have loaned their own vehicles for the helicopter raid must drive back to base and after that they are back in game.
  • If a helicopter lands near the enemy main base, the enemy HQ may be informed by game masters with a 5 minute delay.

 Anti tank soldier

  • You can destroy vehicles by using a 40mm TAG palading color powder grenade/similar commercial colored powder projectile. You can buy these yourself or rent them from game masters in advance. Only an at-soldier can use these grenades.
  • Using other than Tag paladin grenades/similar commercial colored powder projectile (for example TAG Reaper, Archangel, Velum, Pecker) is strictly forbidden! Intentional use of other grenades is followed by removal of the player from the game! The Pecker training grenade can only be used at the base for safe training.

  • There can be only one at-soldier for each group (group size min. 4 players) and he/she must wear an at-soldier patch or armband.
  • A Paladin/similar commercial colored powder projectile must not be fired from a vehicle unless the launcher is attached to the vehicle structures/gun. In this case, the group using the vehicle must not have another projectile launcher in the same group. If there is a anti-tank player exiting in the vehicle, he may not shoot the palading until both of his/her feet have touched the ground and the person has firmly exited the vehicle.

  • There must be one armband on both hand and both must have player ID number written on it. The Id number can be obtained at the registration.
