Worms 2: Armageddon
The original 2D Worms games were excellent, turn-based strategy games with plenty of weapons, and wacky humour. We'd say the series peaked with Worms: Armageddon and Worms World Party - both were great - but after becoming 3D, it began to lose its way.
With the cost of games development increasing it became harder to justify a simple 2D turn-based strategy game. But in XBLA, PSN and Steam, Team17 now have the perfect platform to return to the classic 2D Worms format, and they did.
Worms 2: Armageddon is the old Worms gameplay that you know and love, but refined and enhanced. One of the best Worms games yet.
