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.

Acclaim Entertainment was slated to publish the game in North America,[1] but it was never released in that region.

A Sega Saturn version of the game[2] was scrapped during development, at least in part due to Acclaim (who would have published it in North America, as with the PlayStation version) withdrawing support for the Saturn.

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

[1] GamePro's Gideon commented, "Although the graphics and sound effects are above average, the overall game experience is too chaotic; in fact, at times it's difficult to identify shots onscreen or to differentiate your own firepower from that of your enemies.
