Tomb Raider 4: The Last Revelation Cheats

this cheats needs 7.8 trainer other wise it will not work

If you have the grenade gun, it can also double as
a depth charge launcher. Point at a pool of water and fire. The
grenade will sink slightly and explode. Normal ammunition sinks
slightly deeper.

In big room in the Chambers Of Tulun where the man that makes shockwaves chases you, wait for a gold beetle to appear then start running around. The beetle will grab you and you will hover around. If you move too much, hit a wall, or get hit by that man, the beetle will let go, slice up your neck, and you will take damage.

--The first skull is at the beginning toward the left.
-- The second skull found is in the shallow water below the very first jump you are instructed to do.
--The third is below the running jump section of training.
--The fourth one found is in the water of your swim training session.
--The fifth one is found during the outdoor sequence where the old man is fighting two of the wild boars. It's around to the right, all the way into a right hand corner.
--The sixth one is on the floor on the right side of the room where the spikes are near the exit door just before Lara goes out to learn to crawl through the crawlspace.
--The seventh one is the one in the crawlspace (you called it the fifth one.)
--The eighth one is on an elevated ledge/walkway that's off to the right where Lara follows the old man up the ramp just before he makes the speech about going left or right depending, because going left is harder.
