One word. Hilarious.
Pros+: Stragedy, and lots of it are well put into the game; Controls are nice and makes movement easy; Simple graphics look nice and everything is animated well; The worm's are hilarious with pratically everything they say, and sound effects are nice; Multiplayer is a must for the whole package; Original art design; Many crazy weapons at your disposal.
Cons-: Not all the controls are well thought up of; Graphics look washed out and don't look clear; Music is bland and boring; Single player is dissapointing.
Overall: If you are looking for a good mulitplayer experience then Armageddon is the way to go, if not it's still a good game with some flaws.
