If you would like to play the map solo, type 'map zs_viaduct_v7' into the console once you have fitted the map into your TF2 directory and, after clicking 'FIGHT', type 'tf_bot_add' to create a dummy second player so the match will start. Newest version is version 7. Credits to jack5 for helping me out with the map. Map conceals several zombies-first features, only the curious and the adventurous can discover their secrets. Version 2 (zs_viaduct_v2) A barrier at the blue spawn prevents red team from attacking the zombies early (aka during the zombies frozen phase). Zombies can walk at the barrier or strike it with their weapons to break it Red spawn changed slightly to allow parkour to an easter egg at the very top An engineer model added to the map to act as a decoy for players hiding in red spawn Medium health and ammunitions pack added to the secret tunnel Fixed an exploit spot on top of the rocks near the control point Version 3 (zs_viaduct_v3) Lag fixes to the red and blue spawns The health and ammo pack previously in the tunnel were changed for only an ammo pack Texture updates Bridges to the red and blue house were removed to allow humans to set up on the top floor Gates blocking the upper floors of the houses were removed VIP club room! Password required to enter via keypad Version 4 (zs_viaduct_v4) Missing texture and sound fixes Fixes to props with bad lighting Changes to the VIP room to avoid zombies or humans getting stuck in each other Narrowing of the red spawn parkour platform to give zombies more room to jump up Dancer models in the VIP room have been moved out of the way due to players having an urge to attack them Fixed a light in the side tunnel Updates to existing textures and sounds Lighting fixes in the VIP room Version 5 (zs_viaduct_v5) Sound fixes (Restored buggy ambiance, sounds do not require restarting anymore) Traffic change to the VIP room for stuck prevention Texture updates Much more difficult red spawn parkour (Let's see you try to get up there so easily now!) Removal of the fence above the red spawn More easter eggs! Version 6 (zs_viaduct_v6) More fixes to props with bad lighting Elimination of an exploit introduced with changes in v5 (You see, I knew you guys would cheat so I came prepared) Texture updates Version 7 (zs_viaduct_v7) Complete removal of the platform in the red spawn. This area became too unmanageable and needed to be removed for balancing. Addition of a smaller platform in the red spawn to replace the original Movement of a prop to make it easier for zombies to reach the platform in the red spawn Parkour elements moved to prevent players from getting stuck on beams and pipes. The parkour is slightly easier as a result of this. VIP room has significant texture and lighting upgrades. Song was not changed. VIP keypad has shock protection. Do not attempt to open, it will hurt you. Can only be deactivated by specific people. VIP keypad combination changed.
