Brain stem and the added health seem to be working though the health honestly seems a bit off, in beta nightmare mode and the other nightmare servers that seem to be working all have the zombies set at I think 1000? I'm right. Here's Riley's post
"Nightmare Mode details:
Overall zombie count increased by 50% in objective mode
Base zombie health increased from 500hp to 1000hp
Bite infection chance increased to roughly 75% at full health
Disabled token respawning in survival mode
Brain Stem functionality enabled
Friendly Fire increased by 50%
Disabled Player Names
Brain Stem functionality details:
Players can insta kill zombies with a single gunshot if they carefully aim for a certain region of the zombie's head (generally the middle part)"
I'm unsure what the health of our zombies are currently set to but I think it may be a bit less. In beta and the vanilla nightmare servers that are working correctly I've tested out almost all weapons and a good one I've been using to test to make sure nightmare is working is the pipe or crowbar, basically the same damage, in fact I think it is besides the stamina consumption and weight of themselves, that's besides the point though. The point is with the pipe or crowbar with non charged quick hits it should take 4-5 hits to the head to dispatch a zombie walker, in our server it's taking 3 which leads me to believe it's off a bit.
Also infection is still not working properly. Over the course of multiple matches I let myself get bit multiple times without being infected, unless I have the luck of a god I am pretty sure the infection cvars or whatever didn't update.
I saw you updated the map listing, so far I haven't encountered any crashing maps or maps acting oddly, it's up to you but I'd personally like to have nmo_oc_waking_dead back in the map listing, the map isn't broken, it all works fine except for the respawning bit and the words not always showing up for objectives, but most everyone I see play on our servers has played ocwd and knows where to go in the map incase the words don't show up.
I guess one more gripe is nmo_keystone(some random number and ****) seems to be having trouble downloading on some players end though most if they wait a minute or two seem to load it up fine, I'm pretty sure it's just cause it's such a large map.
Anyways thanks ahead of time, sorry for all the trouble with the server!
If I can help in anyway more just shoot me a messsage on steam or something.
