Although Monkeystrike isn't released yet, you can already read the MS 1.0 manual and gain closer information on how the MOD is played. I recommend to read it, so you won't get your sorry, nub butt kicked that badly when you play it for the first time ;)
Good news for mappers too, the downloadable, offline version of the manual contains additionally a remade mapping manual, which explains the entities, gamemodes and other stuff you have to keep an eye on while making your MS map.
