Tredmill is an infection map based on Blackout.
It has many crooks and nanny's to hide in, some traps and buttons and even (wait for it)...
floating objects!!!
Ammo is scarce but guns are in large numbers!
There are a few safe rooms and some other cover to be found.
The name of the map actually is: A Tredmill
Because the game variant that comes with it is called running
The end result is:
Running on A Tredmill

Each round is different as different objects spawn at different times!

Here's some pics:

This is were the humans start with a few weapons to grab (minus the spartan lazer)

This is were the zombies spawn, a grav lift spawns at the end of the hallway after 30 secs to let zombies out

This is the first switch; destroy the grav lift to either have one impenetrable base or to let the zombies out earlier... it's a 50/50 situation (results and grav lift spawns at start of round may vary) This also allows the zombies to get onto the platform below this easier, without the grav lift, the zombies can jump through a gap and land right next to unsuspecting survivors... you'll know what i mean when you play this ;)

One of the floating platforms, this one is a hard one to get to, but it pays off to be up here!

The other floating platform, multiple ways to get to it! includes grenades, a brute launcher and a flare

This grav lift may also turn on other things! (destroy the pallets to block off the hole in the roof!)

This is were the zombies come out after the brav lift spawns

A neat little hiding spot, hide in either box or both in the small gap in between!

An example of how dark it can get, the flamethrower spawns here after 3 mins!

This is were the rocket launcher spawns, it never respawns after use!

Plus: There is also a secret area where there are great weapons and lots of them, if you find that area, there are lots of great benefits!!!

(I changed a few aspects of the game variant :D )

A Tredmill v2;
Want a better version of Tredmill? Sick of the humans finding the hiding spot and kicking your ass? Do you want another hiding, and maybe have the zombies not coming at you at the very start of the round? Sick of that bloody human with the flamethrower?
Then Tredmill v2 is for you!!!
With one more secret hiding spot so that you have choice !!! :)

I made this map very quickly as something to pass the time, it was not as well thought out or neat as my upcoming maps, so if there are some odd things about it...
then oops, my bad!
