I bought 13 Sentinels not expecting much, I was very pleasantly surprised. The story is convoluted and pretty much batshit insane, deploying every sci-fi trope since the 1980's, but the way they unravel it, I didn't have much trouble keeping pace. Ended up getting the Platinum trophy and was immensely satisfied for doing so. Can't remember the last game I can say that about.
Also, while the battles look like something from the early 2000's, the absolute hordes of enemies coming at you is something to behold, many a time I was sat there thinking 'how the fuck am I going to win this?!'
