This sequel has many improvements over the first version. There are many more weapons, and also better graphics. There are realistic-looking explosions, and many more options. A menu was added, and now you can play a regular game (and choose from several maps, or make your own with the included level editor), play a team game, or set the options. The controls are not explained in the game, but you can find them in the data/binds.cfg file. Or just try out different keys to see what they do. The only downside to this game is that the enemy stick men are incredibly hard to beat. They have excellent aim and they move really fast, so it's very hard to catch up to them and kill them. Sometimes it's easier to press X to put the game in slow-mo, so that you can have a little more time to aim and press the right keys.
