So, KarBOOM's still happening. Now in (and I apologise) Unity 4.
There's actually nothing in Unity KB that I couldn't do in GS KB, feature-wise. And since I'm using the free version of Unity, there are visual things I can't do that I could do with my edition of GS (shadows, reflections and bloom, namely). But Unity supports Mac and Linux as well, so Unity it is.
There are now 3 weight-classes, the middle one being the regular KB kar; the smaller one being lighter (easier to knock around), having more vulnerable weak spots, and being more agile; and the bigger one being heavier (harder to knock around), having harder to reach weak spots, and being quite sluggish.
