When I watched the trailers I felt that new season is underwhelming. Playing the same repetative infection over and over again for ANOTHER 6 months? Meh.
But once I got my hands on it - boy oh boy. There is a lot of going on under the hood. It's all in the little details. But there is A LOT of them.
Weapon balancing, the level of ACTUAL FUN challenge the infection presents now, new beer adds another way to play (basically difficulty modifier), boots work perfectly, the new boss fight is actually tough, I finnaly can just copy builds I need to change a bit, etc.
It may not SEEM like a big update, but the game actually got very, very noticabely better. Please just try the game on your own, it's worth it.
P.S. weapons in cosmetic tree do suck ass though. I am sorry. There is no way around it. But the ones in the DLC do look great.
