For CO-OP, same keyboard, one player with arrow keys, the other with WASD, or if you wanted customizable.
I tried updating my display driver and tried the old version again, and updated my computer, but it still crashed. This isn't the only game, so it isn't necessarily because of something on your end, except for whatever the game requires. I have been fighting my computer for years now on this. Updating won't help most likely. At this point, it must be a hardware issue. But thanks anyways. I hope I didn't scare you any with the title. You can delete this thread or whatever so as not to startle others.
