Cheat to Unlock All Missions in Ultimate Spider-Man (PS2)

No such cheat code exists. Ultimate Spider-Man (PS2) does not have a "unlock all missions" cheat. The game uses a linear, story-driven progression:

• Complete main missions → Unlock next chapter / area.
• Side missions (Combat Tours, City Events, Races) unlock as story progresses or by finding markers.
• Playable Venom segments unlock at specific story beats.

Available Cheats (Enter at Main Menu / Pause)

• Unlock All Costumes: `Up, Up, Down, Down, Left, Right, Left, Right, Circle, Square` (varies by region/version).
• Invincibility / Infinite Health: Action Replay / GameShark codes only.
• Unlock All Concept Art / Comics: Collect hidden tokens in-game (no cheat).

If You're Stuck

• Check GameFAQs for mission-specific walkthroughs.
• Use **Chapter Select** (unlocked after beating game) to replay any mission.
• PC version (if you have it): Trainers exist for mission skipping, but PS2 = no.

Play the story. It's widely considered the best narrative Spider-Man game (Ultimate comics adaptation). The Venom gameplay is unique.
