Wise thread. While generally we avoid adding new stuff in until we finish ones that are already in process or were planned earlier, but it's always nice to have a request list on a side for later on.
I agree that shove is kinda essential so I went along with it and added in. It should be available in next release, or if you are inpatient grab it from the source -> In that case, set server as unpure so other clients using official release can still connect and play.
FYI, I've hook it under "activate" button. Meaning, you use same key for pushing players away as you use for opening the doors as there's no point making a whole new key for it and forcing users to bind a new key for something like that...
As for more ammo. Fretn is currently working on a "buy" feature. Where players can buy more ammo, weapons..using points they've earned along the game. At the moment I'm not sure if this is whole new game type or will be available in all game types, but he can say more about it.
