The combat was fun, traversing the island was fun but after you take out dialogue, cut scenes, QTEs and set piece events you aren't left with much actual game. This becomes doubly harmful for this particular game because there is no option for NG+, when you are finished with the story you are left on the island with next to no enemies and just generally nothing to do.
I really wanted to put some more time into the game but there isn't anything that interests me left to do. If you're not into looking high and low, playing find the tiny hidden GPS cache, after you've finished with the tombs there isn't anything to do really. Actually playing time was probably about 7 hours on hard difficulty w/ finishing all the tombs. 15 hours if ya include all the down time.
Everything about the single player campaign is fantastic.
The entire game feels like a struggle for survival where at every turn you're fight against the odds. You really begin to understand what made her into the modern day tough as nails Lara Croft. Every fight has you on the edge of your seat and leaves you feeling great as you step out of the situation as the lone survivor.
The weapon customization is great especially the fact that you need to search for more upgrades(via crates and chests). The character customization has you choosing(early in the game) between many options, I often found myself choosing the skills that I needed at the moment to survive instead of mapping out some end game path.
The fights are fun and interesting often with many different ways to do it. Stealth or brute force are often the basic choices with sub options of melee, silenced weapons, bow, exploding barrels, or just outsmarting them.
The platforming sections are fun but are mostly simplistic so don't expect a great challenge there, the tombs are a joke as far as figuring them out.
The multiplayer is terrible. Interesting for about 1 match in each mode until you realize that there is a Call of Duty pretiege system and you have to do the same thing over and over again to get to the top. The game modes are mostly unoriginal and the maps are skewed to favor one team or the other with spawn camping easily an option.
If the multiplayer were better(or just not in the game) I would give this game a 10 without hesitation.
