The gameplay itself is fun. Weapons function as intended and have several branches for power-ups, which bring variety. But progress slows to a crawl once you get to level 25ish. I was doing well, albeit with some challenge. But now, I can do almost no damage to the elites. Level 25 is an obvious progress throttle. It pushes the game into pay-2-win status. Rather than skill. Again, great potential wasted because of either greed or an overlooked progression issue. Will upgrade score when fixed.

I really do enjoy games like this. I've played a bunch of them. However, this is very pay to progress, and it's not cheap. Just the monthly skip adds is 22$ USD. Rewards are very minimal, so expect to grind forever. The weapons and bots are pretty fun. But again, to level them up is either very, very time-consuming or very expensive. It could be a fun game, but the greed and endless grinding doesn't make it too enjoyable. So many people have quit this game because of this.

Game is quite fun in the beginning. But to upgrade & advance starts slowing to a crawl the further you go. Starts becoming more about time wasting side missions, ad watching & collecting then actually playing the game. Also, your health/defence can be 1 million or even 3 million units but if a zombie touches you, you basically die so I don't understand the point of that whole system. The game is fairly new & has a lot of potential. The longer you play, the more time wasting it becomes.
