The game itself works too, for the most part. It's got a pretty tough learning curve after you get past the first few stages, and the game never really relents from that point on, but as a general rule, the game's entertaining enough to keep you going after losing ten times in a row.
There are two major modes of play -- single player and multiplayer. In the Single Player mode, you pick a team to take the continent of Saustralasia over, the world's best source of swill. The plot is trite and yet somehow humorous, with areas of the map like Hogshead and Arstria. You go area by area, facing off against the various other countries as you march across the country. You start off with untrained grunts, and as you beat the levels, you get the ability to promote the various pigs into different jobs, making spies and bombardiers and pyrotechnics and other fun things.
The game is, basically, a 3D Worms, and uses the same style of play. Each team takes a turn, one person at a time, while the other characters simply stand around. You have an arsenal of weapons that grow as the swine get promoted, and weapons appear on the maps as well. Most levels have a gimmick, like an assault on a fortified location or battling in the trenches. It's all timed as well, so you can't just wander around aimlessly for as long as you like. Precision and speed are the key.
In Multiplayer mode, up to four people can hand off the controller and fight each other. There are two different modes of multiplayer -- Survival, where you simply want to be the last team alive, and Deathmatch, where you want to kill more of the other person than they you. There are quite a few preexisting levels for you to play on, and the game can generate a near-infinite number of random levels in both modes to entertain you as well. Each level has a code, so you can write it down if you found it really enjoyable.
