Worms 2: Armageddon is a follow-up to the downloadable version of Worms that was released in 2007 (and not a mix of the earlier games Worms 2 and Worms: Armageddon as the title may imply), and it features a new 30-mission campaign, three tutorials, and five secret missions in addition to the original game’s already extensive content. There are a total of forty weapons to choose from, some of which are returning favorites (such as the Holy Hand Grenade and the various sheep versions), while others are brand-new additions (like the Bunker Buster and the Buffalo of Lies).
The players take control of a squad of armed worms that fight on a randomized two-dimensional battleground. The players take turns controlling one worm at a time, and throughout their turn, they can either position the worm until the time limit is reached or use a weapon that can be chosen from a menu. The worm that selected the gun will use it against whatever is in the immediate area using direct-fire weaponry such as shotguns and Uzis. The player can aim thrown weapons like grenades and bazookas, and the constantly shifting wind controls their trajectory. When explosive weapons (such as airstrikes or bombs) are used, holes are blown in the landscape, and any surrounding worms fall into the new craters.
The vast majority of weaponry can only be used a certain amount of times on each map. Every worm in the team possesses its health meter, which will perish when depleted to zero or when knocked off the ground and into the water. The game is automatically lost by the team that runs out of worms first.
Players can compete against one other offline or online, as well as against the game’s single-player artificial intelligence. The multiplayer mode includes a variety of game modes, such as deathmatch, forts, and races, each of which has its own set of leaderboards. Players can establish new teams with custom names, headgear, voices, and attitudes as they progress through the single-player campaign, allowing them to unlock additional personalization options.
