Imperium Airsoft

Standing rule set at IMPERIUM!

The Airsoft Basics:

  • The number one rule at Imperium is the infamous ‘Wheaton Rule’, which is DON’T BE A DICK. If what you are doing is going to spoil the other person day, or is negative in any way, DO NOT DO IT.
  • Make sure everyone else is having a great time, be positive, helpful and show great sportsmanship, if you do that, the other 199 players will be doing it for you and your day will be fantastic.
  • Take your Hits. Call HIT loudly. Keep a hand up. Do not move and follow the medic rules.
  • Don’t cheat call / get angry / swear / shout / or moan.
  • Dead Players DO NOT TALK.
  • Be conscientious, keep safety of yourself and others in mind.
  • No overkill, 2 second bursts only.
  • Avoid headshots and burst fire at close range.
  • No ‘Blind’ fire, use your sights, Identify your Targets.
  • You should present a target when taking shots(not poke your gun through gaps etc!)
  • Be a good sportsman, stay cool, look after yourself and others.
  • YOU make the day, go out to enjoy it, go out to BE SHOT, and be shot well! (not to shoot) stay positive and have as much FUN as possible. Be a great example and role model to others!
  • Your belongings are your responsibility; lock them in your vehicle or leave them at home! Imperium accepts no liability for loss or damage to your belongings while on site.

FPS Chrono and Roles:

All FPS limits are guidelines only, we will measure for acceptable levels using your game weight BB’s and measuring for Joule Muzzle energy at Chrono.

All Guns to be used must be subject to Chrono after booking on and carry the appropriate tag. We will random Chrono throughout the day.

The HIT Ethos:

Honesty, Integrity, Trust. – Be honest, operate with Integrity and trust in others to do the same.

Abuse of our ethos or rules could lead to an immediate ‘Request to Leave’ or RTL, If a serious incident has occured you may at our sole discretion be immediately and permanently banned. If you are requested to leave, the reason will be explained to you, and you will be escorted from the site without refund. Any abuse of staff during this process will lead to an immediate and permanent future ban and reporting to all sites in the area.

Non Hit taking, leading to an RTL:

  • You will be asked to leave the site if you cannot take hits.
  • Players who are unable to take hits will be ‘RTL’
  • Being new, ignorant, excited, tired or being a power player are not a defence.. take your hits or do not come.

At our sole discretion a player will get the benefit of the doubt on their first offence with the exception of an experienced Marshal, or player marshal teamed with the offending player, being witness to an obvious attempt to play through a hit. An example being, a flinch or expressing pain after receiving a hit, but carrying on play, a breach of our HIT Ethos and instant RTL.

Generally speaking, a player who receives an RTL for non hit taking only, is welcome to play at a future events but is subject to further RTL’s to a maximum of 3 visits, after which a permanent future ban is imposed.

Behaviours that leads to RTL and typically a permanent ban:

Dishonest play of any kind

Cheating of Chrono or deliberate use of a Section 5 Firearm.

Destruction or damage to property or vehicles.

Unsafe behaviour

Unsporting behaviour

Shouting of obscenity’s.

Toxic behaviour to the detriment of Imperium or others.
