Chambers

The field is marked out, stay inside the boundary.

• On the street side a fence keeps you inside. On the river side you may not cross to the other bank.
• The forest edge and the construction zones are marked with green wire.
• Zones taped off with red and white tape are off limits (safety).
• Outside the safe zone, safety glasses are mandatory at all times. No glasses means immediate removal without refund.
• Buildings and objects must not be moved or removed.
• Windows that are closed stay closed, doors that are open stay open.

• Magazines must not be loaded in the safe zone.
• Dry firing ("test shooting") is not allowed.
• Do not shoot across the safe zone.
• Keep your stay in the safe zone during the game as short as possible.
• HPA players disconnect their adapter before entering the safe zone and only reconnect on the playing field.
• The parking gate stays closed during the event and only opens for departure after 15:00. Access runs through the buildings at the inner courtyard.
• Before the briefing magazines stay unloaded. Loading only happens after the briefing, on the way to the spawn.
• The event runs until 15:00 and you are expected to stay until then. If you really must leave early, park outside the gate or arrange it with the organisation, without disturbing road users or neighbours.

• Marshall instructions must be followed immediately.

• Foul language and aggressive behaviour are not tolerated. Address people the way you want to be addressed.
• Violations lead to immediate removal without refund.

• Smoking and socialising happen during the break or at the respawn, not during gameplay.

• Breaks are announced with an air horn.
• First break from 11:30 to 12:30. Be ready at 12:20 for the restart at 12:30.
• A possible second break (in hot weather) lasts 15 minutes at most: load magazines, drink and get back in the game.

• Shooting too hot at an in-game test means no more playing for the rest of the day.
• Random in-game checks are possible. Over the limit means immediate removal without refund.

• Report for the measurement and test with your own BB weight (checking for straight shooting).
• The marshall helps you adjust the hop in case of under- or over-hop.
• The actual measurement is done with the BB weight of your category, test weights are provided.

• DMR class 1 (max 1.7 J): min. 20 m engagement distance, no shooting inside buildings (shooting out is allowed), no full auto, no "happy trigger finger", only LOW and MID-cap magazines.
• DMR class 2 (max 2.3 J): min. 20 m engagement distance, no shooting inside buildings (shooting out is allowed), no full auto, mandatory 2-second delay.
• Bolt action sniper (max 2.3 J): min. 20 m engagement distance, no shooting from inside to inside (inside to outside and outside to inside are allowed), hop-up set to your own BB weight as at the FPS test.
• DMR classification only applies when ALL criteria are met: single shot only (fixed), min. 80 cm length (at its shortest setting), stock ready to shoulder, magnifying optic, bipod, only real/low/midcap magazines and one projectile per trigger pull. Otherwise the replica falls under the standard category, without exception.

• Only Enola Gay smokes are allowed, other smokes are forbidden.
• In dry weather smokes can be temporarily banned due to fire risk (decided on the day itself).

• Airsoft Innovation 40 Mike and Master Mike are forbidden.
• TAG rounds (oversized projectiles) are forbidden because of unsafe distance and risk.

• When hit, call out loud and clear "HIT-HIT-HIT".
• With a hi-vis vest: show it. Without a vest: hand or replica clearly raised, until you are revived by a medic or walk to the respawn.
• Step out of the line of fire quickly. A hi-vis vest is recommended.
• Shooting at players who are calling their hit (vest, raised hand or replica) is not allowed.
• Dead men don’t speak: after a hit you no longer pass on info or enemy positions.
• Friendly fire: if you shoot a teammate, you take the hit yourself. Aim carefully.
• Weapon hit: a hit on your replica counts as a hit. Call "hit on weapon" and switch to your side-arm.
• Knife kill: only with a dummy knife (real knives forbidden). Tap the opponent, who takes a silent hit.
• Headshots are not rewarded and must be avoided. Do not aim at the head when other body parts are visible.
• Blind fire: you must keep sight of your target. Do not shoot through openings smaller than an open hand.
• Pang rule: not an official rule, use common sense. Within 5 m do not shoot higher than the torso. You may call "PANG" to take someone out. No automatic panging (1 to 2 seconds between pangs).

• Medic rule: a yellow armband (on one leg). A hit player calls "MEDIC-MEDIC", the medic takes off their band and hands it to the hit player, who calls "BACK IN GAME". One medic revive per life, a second hit means respawn (max. 3 steps out of the line of fire).
• Respawn: the spawns are pointed out before the game. Do not take off your safety glasses, do not shoot from your respawn or into the opponents’ respawn. The respawn rule (1, 3 or 5 players) is announced at the briefing.
• Team bands: everyone receives a band at the briefing. Orange/Red team right arm, Blue team left arm. Ghillie players wear the band visibly, friendly fire caused by a hidden band means the ghillie player respawns.

• Only biodegradable BBs are allowed, maximum 0.46 grams.
• Eye protection rated EN-166F or higher, ski goggles are forbidden.
• Mesh masks and mesh goggles are currently tolerated but strongly discouraged. Eye damage from non-compliant gear is at your own risk.

• Single shot only: the roof section of Chambers, from inside buildings to outside, the pool zone at the villa and the villa terrace.
• Full auto is allowed from outside into buildings (unless it is a single-shot event).
• Base camps are mission locations: you cannot respawn there and must defend them when they matter to the mission.
• Missions are explained at the briefing or indicated at the respawn. Missions are added or dropped throughout the day.
