Beta came and went with no fanfare round here. Having played it, I don't hate it. The single mission type wasn't particularly exciting, but it wasn't bad overall. I had fun with it. It's not a priority, but I think I'll get the game. But as I've said before, used for 10 dollars or less somewhere down the road. At its heart, it's like a co-op mgs5 loaded with crazy mods. The structure of a good game is there for me, it remains to be seen if all the pieces fit together well.
It may be an obvious cash in on the metal gear name, but there's no harm in buying used. Still plenty of honest devs at konami that didn't have a cult of followers to fall back on, they're probably still doing the best they can, kojima or no.
