Underrated - If You Like Loot!
OK, I tried this game, and it was a bit boring. Uninspiring. A waste of time.
A few months later, I tried again. Before, I'd tried the strong melee character. This time, I chose the all-rounder class. Wow, what a difference! I really had a much better time!
There's some fun loot, some fun shooting and blasting, some interesting level design (although ultimately it doesn't improve the game, it's nice to see something new attempted). Some more bad guy variety would have been nice, and the story ends on a cliffhanger... but there's no sequel!!
Otherwise, it's good enough. Worth getting on the cheap!
And if you don't like it after half an hour, try restarting with another character class.
