(Years later) It's a good game overall, gave it 124 hours back in the day. If you think of it as standalone Metal Gear title and not as a Metal Gear sequel/DLC, you can actually enjoy the game. Raiden's adventures are also great, yet with a completely different gameplay style. It's quite nteresting seeing the MGSV engine being use on a totally different game, with some similarities to the franchise, and with some stuff completely new to the franchise. Some missions are fun, and the DIY base management takes it to another level. It can become a bit repetitive after 100+ hours, I must admit, but this game does not certaintly deserve the hate avalanche brought upon it.

I died to a claymore that i just placed and lost an hour of my life. Mid game made with assets from MGSV, it gets kinda repetetive very early and probably doesn't go anywhere later on. The savepoints system is very frustrating (dying form a bug can lead to you loosing an hour worth of progress and your precious life) and alt-tabing somehow leads to logging off from their system and you need to wait a couple of seconds to log in again (i couldn't log in one time and had to restart the game). Overall very mid game, not worth your time and money, they wanted to make a live-service game out of MGS and it didn't really work out, shouldn't have sacked kojima and his team.
