So I just played through the latest build, and I really don't get the melee system.
If you're not conservative with your ammo, you'll have to rely on melee, which means you kick zombies to make them fall down, and then can do a oneshot ground attack on them. Great, except the reaction to melee seems random. So I sometimes had to hit a zombie five or six times for them to fall. Which doesn't sound bad, except that the melee/dodge bar recharges slowly, making it way more boring than it should be. Add to that some finicky hitboxes, especially on the forward kick.
Then there's the follow up attacks. Like in some RE games, shooting certain body parts of your enemies like the legs or sometimes head can stun them - then you can approach and do a special melee move that deals good damage. Except that also seems random, sometimes enemies will get staggered after one shot in their leg, and sometimes they won't even after you empty a full magazine. Their also seems to have two types of stagger, one reasonably long and one super short.
Other than that complaint, it's the same as previous builds - lots of potential but it's not used super well. The game looks better now, especially in the city survival map which feels like it comes from a different game. The manor level is still imo the best, because it has a tighter level design and feels closer to RE games. The city survival map glitched out on me and spawned a dog out of bounds, preventing me from finishing the level.
Then, there's the cave map, which imo has one big problem: it's huge but also boring. The map has several things to do before going to an elevator. I forgot one of them, and turns out that the elevator is really, really far. So in the end I just stopped playing rather than backtracking for 10 minutes to get the one item I needed.
