Well, Havok is in the game (the physics toolkit/thingy/premade-engine/whatever-you-call-it).
And in early vids/screenshots you can see soldiers flying and scattering, physically. 
So what happened? Is it just left in there now, as a cold relic, or is it actually used somewhere?
I mean, yeah okay, the soldiers DO fly backwards for a split second before they fade away, but thats hardly Havok, its just a pre-canned animation. They dont even interact in any interactive way what so ever, which is the entire point of Havok.
Will it ever be implemented propely? Or never?
When i first heard of the game and that it used Havok, the least i expected was that the soldiers in a group would fly backwards as they die, remaining on the ground.
Yeah also, whats the point of removing soldiers when they die? Really, tell me. Because to me it makes no sense.
The reason games remove units on death is to make more room for MORE soldiers.
But...... If the battle starts with 30 visible soldiers, and obviously handles it, why remove them? Why not keep it at 30 visible soldiers the entire battle, leaving their corpses? It's not like there are 100 reinforcements waiting to enter the battle (and your video card memory), they are all there from the beginning anyway, so why remove them before the entire battle is over?
Especially considering that this is a game with locked battles, in the sense that they take place on seperate maps where no new units can enter.
It makes no sense to remove corpses. As it is now it is extremely unsatisfying to see everyone you kill just fade out of existance, leaving no evidence of the carnage taking place. Its basically as if you're just playing with a dice and numbers.
I suspect this is something added as a work-around for the crashes.. But frankly, as more crashbugs and memory leaks gets fixed, these kinda workarounds should be removed.
