For the record my favorite Worms game of all time is Worms Armageddon. The art style, the game play, weapons, level editor, and game layout (options, theme, layout of menus) were all done right. This is when games were made to be bought once, and to be bought as a whole.
I saw Worms Ultimate Mayhem as a recommended game instead of Armageddon. The first thing that caught my eye was that this game was the 3D version of what I loved so much. I figured for the on sale price, I'll give it a shot. I can tell you that I am not at all disappointed with my purchase (except that Worms is still a turn based game! I wish they would make a real time one - how? Well I'm not getting paid to make or suggest games). Seeing worms in 3D is phenomenal, and the art and them style they chose to go along with the game just fits it perfectly. The game play is just as good as ever, however will take some time to adjust and get used to the new range/power system. I didn't know a worm could throw a grenade three football fields away from the map. Lesson learned.
Game play itself can be seen from first person or third person worm view. Weapons are varied as usual and are cool to use and shoot. The explosive or corrosive materials found around the map can also be used to eliminate your opponent. Does the 3D land disappear after you blow it up? Damn right it does. How are the camera angles? Actually quite consistent when using weapons, can be a bit confusing or frustrating when simply observing the map. I find that even with unchecking the inverse box for camera angles sometimes it turns itself back on. This is usually fixed by simply squaring the screen with the worm again. That's essentially the only complaint I have is the camera controls.
This game does have CONTROLLER SUPPORT - which is greatly appreciated.
This deserves an 8.1/10 as worms in 3D with the game play and art style they chose, I'd have to give it a .1 over than my solid 8 average. It is a fun game - and can keep you busy for a while with the story, challenges, or just a quick match.
(I did get this game on sale :)
