Where does it fail in your opinion?
Weapon models look oversized and off
Weapon feel/sound is quite joyless. Doesn't matter if it's gun/melee/grenade, they lack heft.
Lack of ammo
Utterly useless AI (bots and mobs)
Dull and basic level layout
Boss type mob spawns in fog, instantly KO's 2 people - don't have the firepower to kill it, 1 person ran past and it despawned
Blood and enemy models look average at best
l4d was 2008? Over 13 years of amazing community ideas to pull from, and this is what we get for £50? It's a joke.
Anyway, this is just my thoughts after a short play session with a few mates. I'd love to be totally wrong on full release but not a single aspect of what I saw gives me hope.
Sorry all doom and gloom, hope it's a different experience for everyone looking forward to it.
