There are other FPS's with Co'op but still yeah Blackshot is pretty cool, the graphics are better than CA's and there is lots and lots of blood but no weapon customization wich sucks. Not overall I see Blackshot and CA's as possible equals. Right now though CA's is going through an Unforseen maintinance. ALso for those that do not know CA's new patch has fixed ingame clan chat and now if you have pulled the pin on a nade but died before you could throw it the nade now drops on the ground and explodes also knifes have a secondary attack now.
