Nick Fury, Agent Coulson, and Maria Hill are conversing back and forth with Tony Stark. When Hill gets a notification that there's a disturbance at the Raft, Iron Man and Hulk are dispatched to investigate. While at the Raft, they meet up with Wolverine. After hearing a siren Iron Man, Hulk, and Wolverine make their way around - eventually encountering Whiplash and the Leader.
Once in the main holding area, all the supervillians are released - including Magneto, who destroys Iron-Man's armor. Hulk and Wolverine then follow Magneto and Sabretooth. After reaching the launch pad, Magneto leaves with Mystique in a helicopter - leaving Sabretooth to help Abomination fight Hulk and Wolverine. Sabertooth and Abomination are ultimately defeated, and Captain America arrives at the location to help the heroes.
