You see an enemy, you get out your BFG and blow em up. That is basically what Ratchet: Deadlocked is all about.
Throw in a meaningless story and you have what seems to be a shallow run and gun shooter with a few platforming elements thrown in. Right? WRONG! This game is not the bad, hit the same button and repeat ad nauseum, kind of shallow, but more like a private hot-tub with whirlpool jets kind of shallow. This game is just like a hot-tub.
You come home from work late, stressed and tired. You get in and its hot at first too hot, but slowly you start relaxing and letting the jets take you to a whole another realm filled with over sized guns that need constant upgrading and endless streams of poor poor enemies that get blasted into a million pieces. Long story short, this game is great, relaxing, stress relieving, upgrade heavy, fun with a story thrown in somewhere. RENT IT! NOW!
