So i've been searching for a multiplayer co-op shooter game like contra 1-2-3 but I just can't find one Please If you find something like that side scrolling screen 2d etc, Just something like contra but multiplayer.

Thank you.

Try Soldat
I think it's what you're looking for
"I think"

Ahh, Contra. Man, I remember playing that when I was like, 3. Fucking loved it.

Anyways, with Soldat, you use your mouse instead of fixed shooting. It's co-op, but only with another computer. Also, there are no 'levels'. Soldat is just free-for-all/capture-the-flag etc styled shooting game.

Me though, I have no idea.

I played soldat before, You can't compare it with a contra game :l.
I mean that its boring after some time.
