For all its flaws, you may like me still find yourself playing hours at a time. My recommendation is to come into this game without the lofty expectations and just enjoy it for what it is: a fun shooter with semi-MMO elements.
Incredibly fun, addicting game; It's a rough hybrid of the loot system of Borderlands, the gear system of an MMO, and the combat system of Halo; Once you finish the story and reach level 20, there's still plenty to do, making this a game worth the value.
The game leaves a lot to be desired in some respects; The story feels like it got stripped down, with the underlying lore there but nothing really fleshed out; The loot system is incredibly frustrating as it's completely random.
