nice Ark. I got the copy of insanity, thanks. Do the bad guys ever start walking faster? I was kinda expecting that but they keep going slow it seems.
Eventually they do, not that it really matters because by the time you hit the Orange guys, you start getting lazerraped.
Its a problem I ended up addressing in Insanity X.
The original Berzerk doesn't really have super fast walking robots ever either. They do start to come a bit faster, but the lazers demolish you before it matters
You could try Hyper Mode. The robots are on coke in that mode.
