tl:dr I don't play coop - don't ask.

I don't usually play P2 co-op as I'm fairly certain I would infuriate most partners. I take a very slow, cautious, exploratory approach to solving test chambers. Plus, I'm a bad shot and my reaction time is slow because I'm an old fart.

With all that said, I would welcome a chance to explore the co-op campiagn with a partner of similar (lack of) skill level, or with an extremely patient skilled player.
