Map22: Gonna Never Have To Die by RottKing and skillsaw. LOVE this map, there seems to be a lot to do (and there is) but once you know where things are, it's over before you know it and you feel like jumping back in. Map23 by esselfortium bring yet another palette cleanser before the spicy final dish in map24.
