Lara won't turn her back on you if you cheat...but are you sure you've tried everything else?
I'm a firm believer in doing whatever you want to do to make your gaming more fun. So if that includes cheating, then go for it. But if you're stuck and you don't want to cheat, if you can't get certain codes to work, or if you just want to explore all your options before resorting to cheating, here are some ideas.
WALKTHROUGHS: Obviously, since walkthroughs are the focus of this site, I recommend you check out the one for the game you're playing. The solution to your problem—whether it's a boss fight, a timed run or difficult jumping sequence, a missing item, technical glitch, or whatever—may already be covered.
GAME CONTROLS & STRATEGY: If you're a new raider, or if you just want to fine-tune your playing skills, check out my Controls and Strategy pages. The first links to printable pages for each game listing all Lara's moves, how to use the different vehicles, and how to navigate the in-game menus. The strategy page goes a little further, with info on finessing moves, choosing the right weapon for the job, conserving health and ammo, and other helpful tips.
Some of the info there is pretty obvious, but there are a few tricks unique to this game. For example, the strategy section on setting up jumps in Tomb Raiders 1-5 can save you hours of frustration, since jumping works differently in TR than in any other action game.
USEFUL BUGS: Some glitches can be good. The TR series includes a few that allow you to get Lara into places she wouldn't be able to reach otherwise, conserve ammo and even save Lara's life. Check out my Useful Bugs pages for details.
FLIGHT PATCHES: Several of the games have unofficial flight patches for the PC versions. These let you fly Lara out of a bad spot or into a better one. The Downloads pages for each game have more info.
SAVE FILES & SAVEGAME EDITORS: These can be a godsend if you saved your game in a bad spot, run out of health packs or flares, or just have to have a certain weapon a few levels early. Savegame editors, save files and instructions can be found on my savegame pages. There are Windows PC saves for every game, Macintosh saves for most, Nintendo Wii saves for the available games, plus PlayStation and PSP saves for some games.
