I have no physics to offer, but I DO have a game idea for you.
• Three teams
• In the center is the objective, let’s say it is a flag for CTF
• no blasters in the colored no-man’s lands or the middle neutral no-man’s land. This means if you want to get that flag you take the risk of elimination AND dock your team a shooter: I always like trade-offs
• Additional rule: you can only go into your teams zones.
• Shooters: you can choose to target flag grabbers OR pick off the other team’s shooters.
• Unlimited instant-touch re-spawns at the designated areas.
• Could also be done with a Territories setup where all the Territory objectives are in the middle neutral no-man’s land.
