Ratchet & Clank rocks.
Levels are polished, with a strong sense of humour throughout, which doesn't detract from functionality. Difficulty increases well across the game and loading screens are painless. The usual environmental themes are covered, but are freshened. Variation works rather than being a nod to games that came before. The attention to detail is breathtaking.
Weapons wreak well-balanced havoc, and are fun. You start with Ratchet's wrench and bomb-glove, then purchase weapons as you go, like the suckcannon and morph-o-ray. Weapons and ammunition are acquired with bolts, and enemies are made of them. The more carnage you cause the wealthier you get, so the collecting aspect has integral meaning.
The enemies aren't taxing to any but the new gamer. Bosses are better, but still don't push limits. That didn't bother me – I derived a lot of pleasure from the enemy designs. They're repulsive and silly by turn, and where they're too easy numbers increase, so you can go berzerk.
Missions include racing, shooting, and running gauntlets, and are well worked with plot. I enjoyed and got a great deal of satisfaction from tasks set.
Ratchet is a sulky, adolescent critter, and Clank a sweetie. Ratchet has a wonderful range of moves, designed to make you grin as you execute them, with Clank ‘upgradeable’ as his backpack, extending that, but limited on his own. Personality and humour ooze from both, but everyone will love Clank best.
As cameras go, this one irritates, but is better than most. Enemies, as mentioned, are a little flacid, and the odd bug exists, but less than most titles of this scale.
Buy this game. Before going platinum it was great value. Now it's come down it's a must-have.
