For this fan of the L4D franchise, the game feels clunky and uncomfortable. UI is wonky at best. Picking up kits and ammo is achieved clumsily. While the Zombies look good, very good infact. In contrast, WWZ is a 3 year old game with much better gun physics and a more immerse world.
Horde fights in this game are worse than fighting in phone booth. If you are of horde mele, this is NOT the franchise you're looking for.
