HA! I like that gibbing system! I do plan to have dead bodies and gibbing supported but this template will not be focusing on visuals. The game I plan to make from this is going to use only icons for graphics in fact.
I also plan to do Doom style AI and I too am planning to make a single player cooperative project from this template too! The next version will support some new features like a reworked weapons system and a completely new spawn system ill talk about in more detail soon.
Keep me posted on what you come up with though! It would be so cool to see a Doom and Quake style game crop up from this! I would really like to play it!
