"X-Men Legends II: Rise of Apocalypse" is an action role-playing game developed primarily by Raven Software, published by Activision and ported to the PC by Beenox. It is the follow up to 2004's X-Men Legends, and was first released in September 2005 for the GCube, MS-Windows, N-Gage, PS2, PSP and Xbox video game platforms. It is set after the events of X-Men Legends and features the mutant supervillain Apocalypse as the primary antagonist.
Players choose a team of up to four characters from a larger group of characters. As players proceed through the game additional characters are unlocked. The game also features online play for up to four players, a first for the series. New characters are introduced, both X-Men and select members of the Brotherhood of Mutants. A new game plus mode is included which allows players to play through the game a second time while retaining all character stats.
As characters gain experience points players can upgrade their four main powers and other abilities unique to that character. Items found during gameplay can also be equipped to further enhance a character's abilities. Characters can combine attacks to create a combo, in which two or more players punch or kick a single enemy at the same time. The character's special abilities can also be used in the same manner to create a Super Combo. In X-Men Legends characters were limited to four core mutant powers, however in X-Men Legends II each character has several powers that players can assign to buttons. The game also features a skirmish mode, which allows players to fight against each other or against waves of computer-controlled enemies.
