I regret that I have paid money for this stupid DLC
When you think that the normal VRs are hard, then dont download this DLC.
It includes a few funny VRs but at the moment i think that the DLC VR mission 30 is very hard and you need a lot of luck.
(VR 30/ time to beat: 15 minutes for gold)
I dont know if it is the last wave but you have to fight against 2x Grads and 3x(or 4x) fenrirs (two with laser-cannon and two with chainsaw) at the same time.
And this is the part in which you need a lot of luck.
Damn i hope there will be a video-guide soon.
