Lara Croft and the Temple of Osiris

I've created a two-part 100% walkthrough video. It covers every single achievement in the game except the co-op ones and the speedruns, but the co-op are self-explanatory and the speedruns are super easy once you've played a level, since you can usually just run past everything and solve the puzzles most of the time. Contrary to some reports, you CAN get the gold points challenge on EVERY tomb on your first time through in solo play. Follow along with the video below as you play through the game (and part 1) to have your 1k in 8-10 hours tops. A detailed text guide follows after the time stamps for those that prefer it, copied over from the walkthrough I've written for this game.

This achievement is story-related and will unlock when you complete the Tomb of Set for the first time.

Set’s tomb is in the Pyramid of Osiris area. His is the central door at the top of the entry area to the Pyramid of Osiris, and will blast open as you enter the area once tasked with defeating him. Cross over the first bridge and destroy the orb with your light. A 2nd bridge will rise up, and after crossing you’ll see a short scene where a giant alligator shows up. Shine your light through the orb here then light the beacon before he can relight the orb with his flame breath. It will explode and the shockwave get rid of the alligator.

Set appears on the next platform, which has the central pit for the ‘knock 5 enemies’ challenge, so make sure to do that while you’re fighting here. You must set a bomb a little bit away from the pit, then lure enemies around it and run over near the bomb so they hug the pit as they come around. Detonate the bomb just as they reach it to knock them in. It takes a little trial and error. To get the ‘catch 5 enemies’ challenge, lure the first group of skeletons over to one of the orbs and shine your light through it to get rid of it, then step where it was and a blue shockwave will be released. If you catch 5 enemies in it you’ll take care of that challenge. Also run between Set’s legs at the first opportunity. You can just replay the fight for the speedrun challenge.

You have to get rid of all three orbs and activate the blue beacon so that the big blue ghost (Osiris) moves to the middle and holds Set in a blue beam of energy. Then stand in one of the blue flames and shoot from it to damage Set. Deal with a few adds after the damage phase ends and the orbs reappear, then get rid of the orbs and light the beacons again. Barrel-role around with to ignore any straggler adds so you can focus on the orbs. You have to be quick when clearing the 3 orbs and lighting the beacons, as they’re on a timer once you get rid of them.

If you take too long to get to the 3rd orb and get light its beacon, one of the others may have already turned back into the orb, preventing your chance at the damage phase and forcing you to go back and deal with it. So to ensure as long a damage phase as possible, and a successful speedrun, make sure you clear all three orbs fast. Rinse and repeat, damaging him when Osiris is in the center holding him, and soon enough you’ll knock out this rather easy tomb and unlock Bad…doggy. If you get all the challenges done you’ll get All bark and… as well.
