X2

X2 is an arcade-style side scrolling shoot 'em up released during the Team17-Ocean collaboration era of video games that created the Worms series. It is the sequel to the Amiga shooter Project-X. Unlike its predecessor, this game was a console exclusive. Acclaim Entertainment was slated to publish the game in North America, but it was never released in that region. A Sega Saturn version of the game was scrapped during development.

Retired pilot Commander Miner is called out of retirement as he is one of the best and last remaining pilots qualified to take the fight to the invading aliens.

Unlike most shoot 'em ups, X2 allows the player to keep the power-ups they have acquired when they lose a life.
