Ah yes, probably should've had that on the list too. Had to have been one of my favourites for this specific genre, even if it did reek of Borderlands.
Always bugged me that the guns were pretty crap against anything but other humans. Except the shotguns that randomly 1HK with headshots.

Hopefully Riptide will be good/better, I've got that lined up for purchase.

Also, finished Zeno Clash today. People were right - it was pretty damn short, but a lot of fun.
Final impression: "...wut?"
