Ah. I understand now. The rat bastards monetized the difficulty of the point values.
I've now been able to achieve 15k points multiple times, but never with enough time to reach the end for full unlock. The one where the dog grabbed me right at the last hallway hurt the most.
I suspect unlocks beyond the 17k weapon are simply completely out of my reach.
I think I'm going to stop playing this now, knowing that they intentionally made this hellishly difficult for those who don't shell out cash for their buggy releases. It's a bit of a relief, in a way.
I had to tank the dynamic difficulty by intentionally dying 3+ times before each of my actual attempts, otherwise the zombies are just bullet sponges that don't drop the ammo needed to get anywhere close to the point threshold.
Between the excessive hordes that pinpoint your location from all areas of the map, the inconveniently placed fatties, and the constant grabs each eating away 5 precious seconds of the timer, I'm done with this Sisyphean torment.
And yes, the 15k shotty in my version is also to the right of the first area.
Well, I managed to just now unlock the shotgun, assault rifle, as well as the hand grenade in one go, so I can definitely attest to the fact that certain nodes respawn around the map after you hit certain point threshholds. Also, another thing that makes this far easier is the card for 3x chance at critical shots, which gives you a solid 50/50 chance, maybe slightly higher it feels to net a crit on enemies. That said, without that, I'm not sure how possible 15k is without any of the targets respawning. Probably IS just enough if you manage to land near everyhing as a perfect shot, as I had some left over (very few mind you, and I definitely got a fair share of 100 points, and a bit of 50's here and there) once I hit the 13.5k mark. Regardless, yeah, they need to add another way to get points to this mode, or at least increase the targets some I feel. Honestly I feel like the zombies themselves should be worth at least somewhere around 1-5 points themselves. That tiny bit could honestly add up, without being too much of a game changer really in terms of just how much you still need to prioritize the targets.
If you DO manage to unlock the shotty though, things become much easier, as it can kill the big guys in one shot when aimed close enough and at the head, giving you the 15 seconds from them, and they always drop shotgun ammo to boot, further enabling you to kill them as well as others. Strangelyenough though, the shot gun is prettyvariable in how effective it actually is, especially against dogs, though that might just be due to the fact their hurtbox barely takes up any of the reticle given their shape and size. Great tool for clearing zombies and getting guaranteed headshots though. Assault rifle is so far, decidedly meh, low chance of crits, and barely even causes any hitstun more often than not. Pistol overall really is still pretty much the best weapon it feels, with the shotgun having some really obvious uses overall. Hand grenade is nifty, but takes too long to explode to be used without some planning, and it'd likely take ages for me to unlock the rocket, as about 20 minutes or so of gameplay ended up with around 19k, and I'm not really sure if anytargets were still left, maybe a few hidden away here or there that i didn't search hard enough for, but, all in all, its a real grind.
