2 days??? I've been going at this for about 5 weeks and am also about to chuck it all in the bin. I have tried every key combination on keyboard and x box controller at all different speeds etc. and still getting nowhere. What with this plus enemy after enemy you have to defeat and not to mention stupid Steam, after about 14 years it's time to find a new hero. Bring back the old Lara. Edit: Sorry, this is not at Endurance but at Chasm Ziggurat - but the above still applies.
