This is how you do sequels. It's everything fans of the original liked with a lot more polish and about eight hundred times more content relationship leveling and character skills.
I'm not going to sit here and complain about the NPC's being genetic looking and in an entirely different art style, not a big deal to me. Not going to sit here and complain about the zombies being gross, they are zombies. My only complaint, and it's a weird one, is the grind. I feel it's way too forgiving, if not nearly entirely non-existent, and yeah I hear you as you say to me "That sounds great!". Usually I'd be right there with you! I hate the artificial grind devs throw in their game to prolong the scarce amount of content they've included, but with this game, I kind of wish I wasn't burning through the content so fast honestly.
Great game though, shooting feels fine, if not all that impactful, lots of weapons that all behave differently, RNG map layouts of items and weapons during missions makes each mission a bit easier or more difficult. Animations are pretty solid (Wish zombies had better animation blending, getting head shots is tough when their heads teleport to a different position after being shot).
Feels like I'll be playing this one for awhile! I look forward to the DLC releases.
