Looking for a PvE weapon system

[xigaro]

Some friends and I are building a roleplay area. I'd like players to work together to defeat an AI - shooting weapons at drones and such. I'm looking for weapons and damage meter for my players, and scripts/spec for my AI enemies to shoot back.

The weapon systems I've seen so far are PvP only and (for lag reasons) don't detect object hits. I don't fancy scripting my own weapons though :) I don't want players to have to buy their own weapons for a system only playable on my sim - ideally freebie weapons, open source scripts, etc. The LARPS system looks amazing with all the character sheet / roleplay stuff too, but that isn't essential.

Does anyone use a PvE weapons system, and/or can recommend something?
