Not only do we have a handful of bugfixes and tweaks to make gameplay as CS-like as possible, but we also get four new weapons to play with AND a tonload of maps. There are also a few neat glitches you can exploit here: like when you spawn, pressing the up button to change your weapon kills all the bots. Choosing a team twice nets you a free US$ 20 of in-game currency.
