Yeah, well Multiplayer is easy for that exact reason. You can kill each other and get life back... Yes, I know about the camo, but that only lasts so long. I actually got a lucky board spawn recently while playing that part I was initially talking about. I only had to worry about 3 of those badasses, and it was cake.
We dont kill each other for life, if one dies the other just keeps going, dosent head back to let other spawn. If the other person dies then oh well we try again(which only happend once when I laced my friend with a plasma and he ran back next to me lol).
