Oh hey, this forum's dead! Just gonna copy past my impressions from Gamingforce.

So I'm playing through the DS version, it's quite good! It feels like a Worms game, which is something to look for in a new Worms game I suppose. Like Picross, I'm finding the touch screen controls pretty useless, it's quicker and more accurate to do everything with the dpad. Graphics are okay, the worms don't get lost in the backgrounds (which now feature 3D planes or ships zooming around the joint), music ranges from catchy to barely existing. There's a heap of customization as per usual. Voices, skin colour, flags, tombstones, pizza topping blah blah blah. You can even design your own levels.
The CPU AI is decent, which surprised me. Usually they're thick as pig crap and end up throwing grenades in impossible places or try and jump massive gaps. But no! The Campaign mode seems to end with a 'boss' battle every five rounds, they can pretty tough bastards. Puzzle mode's pretty boring so far, I've had one 'puzzle' objective as 'kill the other worms!' Yeah, that's great guys.
The DS version has an exclusive collection of mini-games (I guess this is a law for developing DS games). Blast, Blow and Draw. 'Blow' involves launching your worm off a cliff, where he'll parachute his way around a maze. Simply blow on the microphone to keep him in the air, yeah, bloody exciting! The other two are fairly amusing, however. 'Blast' has you jabbing the stylus around the screen, causing explosions. So if you point to the left of your worm, an explosion will send him flying to the right. You have to guide him around more mazes using explosions. Need to get up a high ledge? Try and juggle the worm with explosions from below, and so on! 'Draw' starts off with your worm standing next to a massive amount of explosives, when you press GOGOGOGO, they'll send him somewhere magical. Before you send him to his doom though, you've gotta try and guess where he might land, and block those areas with new walls that you draw, or maybe place some ramps around that'll cause him to slide to victory. The goal is to get him into.. the goal, but there are traps all over. He might land in a hole before the goal, and you're stuffed. Or a fan might blow him the other way, into the water. Draw a wall in front of the fan before you start, for example.
Oh and almost everything you do results in credits. You spend them in the shop to buy new music, skin colour (how racist let's write a letter), level themes for use in Quick Play mode, whole new missions and and and. I haven't put much into online, but it's been lousy in both games I've played. It supports four players, but I've had massive lag, crashing and other abnormalities. Anyway, my friend code is 159024718642. But aside from that, I'm impressive with Open Warfare 2!
