Hint :
Hint: Opening the Star Locker:
To open the Star Locker, break Hank Redwood's records in Leila mode, then complete the game once. The Star Locker contains all weapons with unlimited ammunition. Note: You may not be able to complete the game normally if the Star Locker is used.

Hint: Door password:
To unlock the room on the second floor of the bikers' hideout, enter "1993" as a password.

Hint: Ramirez's spiders and door:
When you battle Ramirez's spiders, shoot them once then stand over them. Press Action, then guide the spiders towards the door. Press Action again to make the spiders jump at the door. Eventually they will melt the mechanism with their acid blood and you can enter.

Hint: Defeating Ramirez:
To defeat Ramirez the second time, you must get up and shoot out the lights. He will then only throw grenades. Next, get up close and shoot him to kill him.

Glitch: Walk through walls:
Find a location with an elevator with a gate-like door. Hold L to crouch, then press A to open the elevator door. You can now walk through any wall on the current level.
