Why is very body hate the ISU-152 so much? It is not that powerfull. Firstly is have a embarrass little range. (I am sure that in real life it has much longer range)
I tried it a few times. Its shell is highly inaccurate, I have hit anything with that thing. I agree with Pauly3, we better off get a IS-2. But I would actually suggest getting a IS-3.
