I'm still busy working through Beyond Good & Evil - too busy even to play the new Mirror's Edge DLC, if you can believe it - but in the mean time I've got some browser gaming for you.
Cell Warfare is a shameless attempt to recreate the winning formula of Amorphous +. Simple gameplay? Check. Coloured globular enemies? Check. A constant stream of badges and achievements? Check.
It wants to be a dual-stick shooter in the style of Geometry Wars. The arrow keys fly you around the play field, and you click the left mouse button to shoot in the direction of the cursor. It's initially a clunky control scheme but with some practice you'll develop surprising precision. The basic gameplay is fun, but as always with this kind of thing the real hook is trying to score all 78 achievements.
In the end it's more accessible than Amorphous +, if such a thing is possible, although not quite as tactical. Definitely worth a bunch of your time but I can't see myself racking up the four hours or so that I did with Amorphous.
You can play Cell Warfare at Kongregate, or alternatively at Newgrounds, if that's more your thing.
