Game development often lasts for years. And in that stretch of time, studios have their fair share of ups and downs. From humorous game bugs to stress-relieving antics, Game Informer peers behind the curtain of game development. In this entry of Tidbits, developer Vicarious Visions shares secrets behind the development of Marvel Ultimate Alliance 2.

• The final game has over 8000 lines of voiced dialogue.

• Recordings of old computer parts being thrown down the stairs were used as sound effects for the physics impacts and explosions.

• Marvel was consulted very closely on all character and plot decisions. In one case, a piece of concept art for the NPC Justice was re-done to match the hairstyle found in the comics.

• An early bug with a "beam split" Fusion type caused the two characters to get stuck together, connected by a line of energy that damaged foes. This was the inspiration for the "clothesline" Fusion type.

• At one point, a bug with Spider-Man and Human Torch's Fusion caused flames to appear to shoot out from Spider-Man's rear end. This was not adapted into any other Fusion

• Another notable bug was when all the robot minions in the 3rd level were replaced with full-size versions of the Yellowjacket boss.

• Number of frames in pre-rendered cutscenes and between-mission briefings: 76754

• Total number of individual animation files, including those for DLC: over 10,000.

• "Heaviest" character animation set (largest size on disc) belonged to Storm.The average character “bone” count per model was 85, for an approximate total of 16660 bones.

• Of all the playable characters, no two character rigs are identical

• The same motion capture performer portrayed Deadpool and Mr. Fantastic.

• Every day at 2pm, a good portion of the dev team would congregate and do pushups.

• Collectively, the MUA2 team has 131 years of martial arts experience.

• Playable character heights ranged from about 5’6” at the smallest (Invisible Woman) to 8’0” at the largest (Hulk). We also had an entry in the character data for footprint size (yes, this actually gets used). Run around with Hulk and Iceman and check out the difference!

• Stan Lee was first approached by Vicarious Visions to be part of the game at a press event in the Hard Rock Hotel during San Diego Comic Con, 2008. The Narrative team decided his character should be a Senator from New York state, which shares its state motto with his signature phrase: “Excelsior!”

• Over the course of production, team members made over 90,000 check-ins to the game.

• Helicopters were a late addition to the game, and as the design was refined, they were added to more levels than initially planned. This led to the inclusion of a new Deadpool line when facing the final helicopter, “You know what this game needs? More helicopters.”
