It's been lovingly remastered and rebuilt in an entirely new engine. The visuals are gorgeous and it keeps all the extra content (even finishing some for TR3 that never came out).

Modern controls are ass tho. Back or slide flipping are limited to the guns being out and it just doesn't work. The free camera also breaks endlessly to the point where it's impossible to see.

I'd also say that the remastered visuals make some pickups almost impossible to see.

Other than that, pretty damn good.
