Ok I will give this a shot. I have been looking for this game for over ten years. I have no idea of the title.
It is for the genesis or nes, as those where the only consoles we had back then. Ok...
Its between an overhead view and behind view, so its as if the camera is 45 degrees above and behind the two players.
It starts of with two military guys and the opening level is you walking in a path/road with a brownish orange color and trees covering the left and right side of the screen. As you walk forward sooner or later you pass train tracks in the forest and (i may be wrong on this) a train crashes.
This was a co-op shoot the enemies kind of game.
If anyone has any ideas this would be awesome to find again.
Me and my brother used to rent it from our cousins video game rental shop. Even he cant remember this one.
