My biggest concern is that I struggle to find a full lobby.
It takes me about 5 minutes to find a game and then it's mostly cross-play players and I had only seen once that my lobby was full! Even more, I never seen anybody joining mid-game, playing co-op campaign is just boring with 1 person... Just checked the steam charts and l4d2 has ~30% bigger online than b4b and that's considering b4b has a cross-play on multiple platforms.
Another problem with this game is that you can't just pick any random map you like and play it, you have to do them in their order and unlock them one by one. This doesn't sound bad right? But the way game handles this is buggy. I finished Act 1 with my mate and then when I tried to host a new campaign I could only select chapter 4 (The Crossing), which isn't even 50% of Act 1. How is this enjoyable?
Overall the game is needless complicated, the new items system and card system are just a downgrades, compared to l4d2. Game lacks in variety. I can list lots of things this game done wrong compared to what the devs had done in l4d2.
There are some positive sides of this game, I really love the graphics, I like that it's still a zombie co-op game but it lacks in variety and atmosphere as well as has overly complicated features that are just redundant. And of course the biggest problem is if you can't find online matches, what's even the point to play this game?
Having this said, combined with game price, I cannot recommend this game.
