Prepare for Global Worming!

If you like strategy games, you'll love Worms World Party. The basic premise: You are the leader of a team of worms placed on a landscape. You must destroy the other team (or teams, there can be up to 6) of worms using a massive arsenal of practical and crazy weapons.
Not convinced? It gets better:
WEAPONS: There are over 50 different weapons. Some are weak, like the handgun, while others blow huge holes in the terrain, like the ever-coveted Concrete Donkey, which drops from the sky and plows through the ground until it reaches the water. Some are basic, like the bazooka, while some are seeking, cluster, time detonated, manually detonated, and/or randomly detonated. You even have an array of exploding sheep to use; some can fly, others are launched from a bazooka, and still others go under water. The object of all of them is to whittle away your opponent's worms' health down to zero, or launch them into the water, where they drown. If you don't have a clear shot, you can move around the terrain using ninja rope, blowtorches, jackhammers, parachutes, and other tools, as well as numerous different jumps.
GAME MODES: In single-player mode, there are four separate games. You can play a quick match against a randomly generated computer team with a team selected by the computer. You can progress through increasingly harder death matches. You can attempt a mission, where your goal is not to destroy the other worms, but sometimes to get items somewhere on the terrain, or to reach a certain point. Or you can sharpen your skills in training/time attack mode. Multi-player is the obvious better of the two. You can play a match with a team of worms that you create against up to five teams of human or computer opponents. You also get to choose the terrain and game settings. You can also try a multi-player mission, which can be either player 1 vs. player 2, or players 1 and 2 vs. computer.
SETTINGS: In multi-player mode, the game allows you to customize nearly every aspect of the game. Create your own team of worms. Name them anything you want. Then choose their special weapons, gravestone, flag, fortress, sound scheme, and victory music. You can make a human-controlled team, or a computer team with a skill level from 1 to 5. You can create your own game modes, as well. Customize everything from the weapons in the game to how much health the worms have to Sudden Death settings. Then you can save your game mode to use it in later games. You can also create your own terrains, use a random one, or select from a list of pre made levels. You can even take a picture file from your computer and use that as a level. If the game starts to get boring, try the Wormpot mode, where you can select several other variables. You can have a super long ninja rope, unlimited attacks on each turn, lots of crates containing weapons, and a mode where the ground threatens to shake you off the terrain every few turns, plus many more.
OTHER STUFF: If you're alone and want to play against another human player, you can join the party online. This also allows chat between players. If you want to learn about all the weapons, the in-game Wormopdeia will have you up to speed on the weapons in no time, and it also includes background information, behind-the-scenes secrets, and more.
