9. Hunted by Raptors and the T-Rex
Once you killed all six Raptors, the T-Rex makes its appearance. He attacked some of the Raptors and they storm panicking towards you. The first interactive sequence will ensue. You have to quickly press (only!) the buttons shown to you on-screen. Don't press them before they are shown.

The combination here is:

* Down (PC) / Circle (PS2)
to dodge the T-Rex attack
* Up (PC) / R1 (PS2)
to shoot at the Raptor
* Up (PC) / X (PS2)
to jump over the Raptor's carcass

With all raptors finished the T-Rex battle begins.

10. T-Rex Fight
Start shooting right away. Shoot at the huge dinosaur while retreating backwards and performing evasive side-jumps. You will notice that the T-Rex' energy bar is yellow-greenish and a red bar charges underneath. Once the red bar is fully charged the T-Rex will roar, giving you a moment and then attack fiercely. But at that moment he is also most vulnerable. You will need to perform the dodge-and-head shot move a couple of times, so I hope you are familiar with it by now. If not, you probably will be after this fight, however it will take longer. You may also want to look here: Moves & Enemies Keep the T-Rex locked on till you've performed the head shot! Depending on the Combat Mode you use, you might need to press the button for it - as there are many different systems and you might have reconfigured your key-layout, I leave it to you to find out, which it is. It is called "Combat Mode Toggle" in the controls settings, simply look it up in the menu!
Dodge
Once the T-Rex storms towards Lara stop shooting and when the screen becomes blurry wait for the arrows to show up/the image to freeze (not with all video cards) evade him by a roll to the side by pressing LEFT or RIGHT and ROLL. When he did not touch you, you have performed a successful dodge and can proceed to the head shot!

Head Shot
Do nothing for now. Grey circles will appear on the screen. Wait for them to focus on the T-Rex' head and turn into one big red circle (a sound will accompany it), then press SHOOT once to perform the head shot. Again the target has to be locked.

If you hit the target, the T-Rex will stumble into anything nearby. If you are close to one of the spiky roles or any rocky outcrops, he takes even more damage than dealt by the shot. Run towards the lighter spots on the ground before any of the (yet undamaged) spike rolls when the T-Rex is roaring when enraged to provoke him into one of the traps. (If you make him hit all three, it will be a short fight.)

Immediately resume shooting and this whole procedure will repeat itself till the T-Rex' health bar has run down.

Use as many medipacks as necessary, while fighting. It is not a difficult fight but it will take some time and patience.

On the left side by the temple lies another Small Medipack. Opposite, where the upper level of the valley is, lies some 50 Caliber Pistol Ammo. In a bush left of the two spike rolls you will find more 50 Caliber Pistol Ammo.

11. Interactive T-Rex Sequence
The combination here is:

* Down (PC) / Circle (PS2)
to dodge the T-Rex attack
* Up (PC) / R1 (PS2)
to shoot at the T-Rex

I also just read that the next Tomb Raider won't be called Tomb Raider and will be download only and more arcadish.

Hi ya Gremlin, they are dropping the Tomb Raider part of the title and just using Laura Croft in the title. I read it in Game Informer.
