I don't usually write comments, let alone my opinion of a game.
This game is so utterly bare bones and simple, that I fucking love it. I have like 3.3k hours in l4d2 so the first two maps being just a reverse copy of Dead Centre is something I adore.
The mechanics are so simple, I can't help but keep playing.
My only gripe with this game is that consumables just don't work and that Silver Hair girls Grenade Launcher does zero damage to special infected, unless I am doing something wrong. Also that plants and glass are inprenetrable. Also shooting on escalators is kinda buggy. MG girl is just crazy meta, if you pick her you'll always have ammo, especially handy for hordes.
I would unironically love to have more maps and some ability nerfs/buffs, mainly for the regen to not be so overpowered and for the MG girl to not be able to take down a tank(?) in less than 10 shots. Otherwise I will watch this thread in hopes to see more of it.
Also the Saiga is nutty, it can not only snipe, but also has AoE and immense damage. Use it before it gets nerfed, assuming the dev will balance at all.
Edit: Nevermind consumables work, I was just dumb.
