Finally tried the demo.
Yup, just what the videos showed. Combat is, at best, a combination of a PS1 game and a MMORPG. Neither of those have particularly good combat. One is archaic, the other is played for reasons other than combat.
So this game isn't about combat. That means it's about being a lab rat and repeating the same dull process over and over in hopes of a new reward, ie weapon.
It's the heaping pile of crap that it's appeared to be ever since they started showing videos of it several E3s ago.
Such a shame. It was such an awesome premise and that initial CGI trailer they released was great.
