X-Men Legends II: Rise of Apocalypse

X-Men Legends II: Rise of Apocalypse is an action RPG released in 2005 for the Xbox, PlayStation 2, Windows, N-Gage, PlayStation Portable, and Nintendo GameCube. It is a follow up to X-Men Legends.

Story
When Apocalypse kidnaps Professor X and Polaris, the X-Men and Brotherhood of Evil Mutants unite to save them. Cyclops, Storm, and Wolverine meet up with Magneto, Mystique, and Sabretooth at a military prison outpost in Greenland to free the Professor. Upon freeing him, the teams relocate to Genosha to work through the wreckage and find out what Apocalypse wanted with the area. Finding Quicksilver also kidnapped, the teams prepare to return to the X-Mansion, but Apocalypse arrives first. He plants a bomb, which more or less destroys the X-Mansion, and kidnaps Beast, who manages to point the team in the direction of the Savage Land.

The teams work their way through the Savage Land, freeing Beast and hindering Apocalypse's plans, and continue to fight against his forces; however, Apocalypse manages to conquer New York and seize control. The teams work at sabotaging his army and resources, but Emma Frost and Angel are soon kidnapped as well. Angel is transformed into Archangel to act as a Horseman of Apocalypse, to defend Apocalypse's tower. When the teams infiltrate it, they find Beast, too, is working against them under the name Dark Beast; he kidnaps Sabretooth and escapes with Apocalypse and Mr. Sinister to Egypt while the teams deal with Archangel.

The teams learn that Apocalypse's plan is to use Polaris, Quicksilver, Emma Frost, and Sabretooth - four mutants with Harmonic DNA - to power an experiment to grant him massive amounts of power. The teams then follow him to Egypt to defeat him once and for all, after first defeating Sinister and Dark Beast (returning the latter to normal). After besting the final guard, the Living Monolith, the teams take on Apocalypse and defeat him by stealing the powers from his machine. In the final cutscene, Magneto and Xavier part once again as adversaries, noting that Apocalypse was defeated but not destroyed. Beast ponders why the machine did not work properly, wondering if sabotage was a factor. As the X-Jet flies away, Sinister is seen on top of the pyramid, laughing.
