X-Men: The Official Game

Professor Xavier asks the X-Men to return to Alkali Lake to retrieve irreplaceable parts of Cerebro. Nightcrawler is asked to infiltrate the remnants of William Stryker’s base with his teleportation ability since the weapons systems were somehow operational. Once inside, he discovers that Stryker had a backup plan to destroy the mutants — mutant-hunting robots called Sentinels. Working together, Storm and Wolverine find an A.I. module for a Sentinel when agents of HYDRA (an organization of terrorists) arrive to take the remaining Sentinels to their base. It is revealed that HYDRA had designed the robots for Stryker. Inside the ground, Wolverine discovers that HYDRA had employed one of his former adversaries — Lady Deathstrike, who survived an apparent death in X2 after being pumped full of adamantium.
