Lara Croft: Tomb Raider: The Angel of Darkness Hints

While investigating Von Croix's apartment, Lara can glitch the game and get a shotgun where there shouldn't be one in that mission. Before leaving the stage Galleries Under Siege, equip the shotgun and clear the area.

When Lara appears under your control at Von Criox's apartment again, press UP (on the D-pad) and the shotgun should be available again.

When Lara is swimming (submerged), save the game while underwater then load that save. The oxygen gauge will be restored to full.

Choose the Load Game option while playing and highlight any file. Then press R2 + SQUARE. Exit the inventory screen and the level should complete automatically.

Pause while playing, hold R1 + L2 + R2 + TRIANGLE + CIRCLE. The option is in the options menu while playing.

A lot of Lara's old moves have faithfully made the transition to Angel of Darkness:

Handstand - When Lara is hanging from a ledge, press and hold L1 + L2 + R1 + R2 to make her perform a handstand.

Somersault - While facing a ledge, press TRIANGLE then UP (on the Analog Joystick).

Backflip - Walk backwards up to a ledge then hold L1 + X while pressing AWAY (on the Analog Joystick).

Swan Dive (a.k.a., Neckbreaker) - Hold L1 + UP (on the Analog Joystick) and press CIRCLE. Note Lara dives straight down after a little bit of forward motion, and it makes her more vulnerable to "cracking".

180 Turn & Crawl - Hold L2 to keep Lara on all fours; SQUARE makes her head and butt exchange positions while swimming.

At any part of the game where Lara can re-enter an area or room with items, you can force them to respawn with each re-visit.

Example: After leaving the pawnshop, Lara can enter the sewer and there will be an object there. Pick up that item, head back into the pawn shop and you can repeat the process as many times as needed. 99 Health Kits, here we go!
