Well, lot of progress was made during this 15 days, and I'll report some of them... Even those I did just after the Beta 8 release (some of them I did some hour later)...
The Predator has a skin now, instead of the default amplifier skin. Also, I added some nice visual effects...
Just after you pick it up, a neat effect will surround you for a while. The same effect happens when the Predator runs out of charge. (I tried to make something "between visibility and invisibility"... Not it looks much better).
And then, I added a "red mask" to the screen while you're using the Predator.
It may difficult your sight a little bit sometimes, but looks great
