Snipe Them is an Infection minigame that I had made a while back. It isnt exactly the best interlocking, but it gets the job done. Alls I really changed was the Human Base, I geomerged it into the wall so humans couldnt get stuck.
I based Snipe Them off the CS:S map backalley_run, which is a fun map where one team must run through a city without being sniped by the opposite team.

The main objective is to run through the Foundry "City" if your the zombies and to try to make it to the roof of the Human's base. However, the Humans are equipped with Snipers and will stop at nothing to blow your head off.

The Human Base(No way out)

Zombie Spawn.

Zombies spawn behind the Single Box in the middle of the screen. Apon spawning, they have three options. They could jump up on the crate on the left of the single box and jump to the right through the "Tunnel". In case you cant tell, the Tunnel is the Double Box on its back. Note: Its not really a Tunnel, its just what my friends tend to call it.

Upon running through the "Tunnel" Zombies must take the grav lift(Pictured in the above picture) up to the top of the map. Or the "Crates". Note: There is a fusion Coil above the Crates, shoot the Pallet to make it drop.

Now, refer back to Zombie Spawn. The second option is to rush to the opening to the left of the Crate. Upon entering, you take a grav lift up to "The Building". You come up behind the Dumpster and must run towards the Barrels. To the left of the barrels is a window panel you jump up ontop of which brings you to the roof. You come out in front of the Crate.

Once on the roof, you, yet again, have two choices. First, you take the Bridge over to the "Crates". This is extremely risky, but rewarding, as you get a Deployable Cover(No Respawn).

Your second option is to jump off the roof to the Grav Lift Building and then jump across the Platforms.

Now, refer back to the The Crates. In front of them are Stairs leading to the Final Room. Once in the Final Room, you simply have to jump across to the Fence Box then take the grav lift to the roof. Note: There is a Fusion Coil in the Final Room

Now, refer alllll the way back to Zombie Spawn, you final option is to just run forward, toward the single crate and Truck. This is the quickest way to the Roof, but also provides the least cover. Note: To the right of the truck is a Crate, jump on it then your in the Final Room.

And finally, a picture of the Human Roof. You pick up a Custom Powerup that makes you have Instant Kill and are invunerable. Throw the provided grenades down the crevice.
