I played and beat it, and found it rather fun. Gunplay is solid, the TMD is a fun toy to use, and story is alright for the most part. The game also has some great set peices and the Seeker weapon is fucking win. Those damn phase ticks are annoying as hell though, think flood infection forms but faster and do more damage.
The game isn't perfect, but it's ultimately a solid game and rather fun to play. I haven't gotten any of these technical issues some others have complained about, game has ran flawlessly on my computer. Although after beating the game, I have this lingering feeling that the game ultimately feels held back, and that its full potential was no realized. There is just something about the game I can't pin point that keeps held back and not ascend to levels of greatness.
But overall I still had fun with the game more so than most other FPSs of late that just feel interchangeable.
