I had to abandon this halfway through due to the game-breaking Beleram/Mirkwood glitch (that this remained unpatched speaks for the game's lack of polish), but I wasn't that annoyed to let it go. The gameplay is rather simple, with basic hacking n' slashing, basic levelling, and basic loot. I alternated between the three characters each level, yet they play largely the same (and character-wise they're bland). I would've liked to switch between characters mid-level (for the character specific actions), but it seems this game was mainly designed for co-op. It is at least neat that the plot runs in tandem to the main story, and that you get to visit some of the unseen locations.
