from the screensjots, i can see a map editor, that's a nice edition to add to games like this that isn't common in many fps games...nice mate!
also, is it possible to make a weapon creator/editor in the game? (it can let some ppl make cool weapons and use concepts from other games),
and lastly, it would be epic if we had the ability to upload oir own textures to the game (like a workshop type of thing, where ppl can share their creations and stuff)
all in all, this is an amazing project man!
