Zombie Mod, not to be confused with Zombie Fortress or Super Zombie Fortress is Team Fortress 2 mod-gamemode. It’s played on custom-made maps and requires a server plugin to play. Zombie Mod originally came out January 2013. It’s a private mod, therefore only 1 server exists for it.

So what is Zombie Mod?

Zombie Mod is custom gamemode where a team a humans survivors have to fend off an increasing horde of zombies until a timer runs out.

The blue team plays the role of the survivors. Their goal is to avoid becoming a zombie for an entire round. As long as a single player achieves this task this teams wins the round.

The red team plays the role of the zombies. The goal of the zombie team is to turn everyone on the other team into a zombie before the timer runs out. They do this by “infecting” the survivors. Survivors become infected and become zombies once they are hit by a zombie a single time. When this happens the survivor player will change teams on the spot, automatically and can’t change back until the next round.

Zombies infecting players in a single hit isn’t an absolute rule. Some weapons and classes need to hit survivors 2 times. As an example the scout’s melee requires 2 hits, so does the sandman’s ball. If a survivor is hit once by an attack that requires 2 hits they will temporarily become marked. Marked players are covered in jarate and have the word “marked” displayed on their screens. Once a marked player is hit again they will become infected.

A few other note-worthy things about the zombie team are: They can see an outline of survivors through walls. They are restricted to melee weapons and some passive and utility secondaries. They have the ability to instantly teleport to a spawn location by clicking the call-medic button. This ability can only be used 3 time in a round, the number of total times left is listed on screen. And lastly this team passively regenerates health and can jump extra high.

In Zombie Mod every round starts the same. After a short grace period one of the member of the survivors team will automatically become a zombie. At this point and onward more and more players will become infected by the zombies until either the timer runs out or every survivor becomes a zombie.

There are a few mechanics built into the round’s timer. Firstly, the timer varies. The length of a round is based off the number of player on the server. Secondly, the timer fluctuates depending on what’s happening in a round. When a survivor kills a zombie the timer jumps down 1 second. When a zombie infects a survivor the timer adds 5 seconds.

On the screen there are numbers found to the left and right of the round’s timer. These numbers indicate the number of players that are survivor and zombies respectively. The same numbers can be seen by holding down the show-scoreboard button. On the bottom of the screen is the word ‘human’ or ‘zombie,’ depending on what team the player is on. The number to the left indicates the number of kills the player has gotten as a survivor. And the number to the right indicates the number of survivor the player has infected as a zombie.

At the end of every round statistics are shows on screen. The statistics are of how many zombies were killed and how many survivors were infected in total. What’s also listed is how many zombies the player killed and how many survivor the player infected as a zombie.

For balance reasons some weapons in Zombie Mod are either modified or banned from use.

In Zombie Mod the engineer class has heavy restrictions on its use. A single person can only play as the engineer once per map and in total the survivors are only allowed to have a maximum of 2 engineers.

One gameplay mechanic of Zombie Mod is called: the last stand. Basically the last remaining survivor receives a damage and speed boost to help them. One thing to note is that if the last survivor is the scout class, they don’t get the speed boost.

And that’s basically Zombie Mod in a nutshell. A fast passed zombies versus survivors gamemode. A mode were every round consists of camping an area and then trying to kill campers.

Does anyone know the Music played at the start of each round? The only song i know thats in the mod is the Left 4 Dead Skin On our Teeth remix

Anybody think this is like a messed up Call of Duty Zombies mode with campers and a timer?

Intox owns the game mode only, the game is fun hands down but of course the worst community let alone the newest owner who's a complete basement dwelling douche bag had to be the owner of it. (Also of the intox community)

Even then I wouldn't bother to play on their servers unless it was Zombie Mod (can't anyways) because in all reality the rest of their servers are trash even VSH which use to have a crowd and the only reason it doesn't anymore is because the majority of admins are too easily butt hurt and take sides with the people who are causing trouble not banning them and banning the regulars.

All the regulars left and went to Fire Friendly <-- recommended

If you wanna put up with autistic admins on intox, up to you really. (I wouldn't be the only one saying this.)

everyone camps in corners, you get instantly infected so its absurd to even play some classes, i honestly was dissapinted by this gamemode, playing scout for survivor is ridiculous since you have to get close to even deal serious damage

I wish the maker of zombie mod would make more servers or open it to the public instead of being greedy & lazy at the same time.
