Worthy of being in the game - especially the non-Halloween version. However, if we were looking for holiday maps, this would be the top of my list.

Do you know how i can get the robots to work whenever i playtest mvm maps from the workshop? They never appear even after i type nav_generate in the console

- Minor lighting fixes
- Fixed small texture misalignment

Mission Changes
- Increased the starting cash from $4000 to $5000.
- Some of the subwaves will now flow quicker while still giving some break points.
- Increased and decreased the counts of a few robots.
- Changed the Giant Medics to the Regen type. (no pop.)
- The Fast Pusher Pyros are now no longer crit-boosted.
- Tweaked tank health.
- Tweaked spawn times.
- Lots of other minor changes.

The download link has been updated to use the new version. Enjoy!

I'm excited!

This is one "hell" of a map (see what I did there?)

Nice map! MVM has needed an update for years and it would be nice to see this in it

Hmm. What could be the map lore? I know! When sending blutarch and redmon to hell, the teams forgot the gates to hell open. And the zombies are now coming from there lol.

HALLOWEEN MVM! please!

i am a potato!

Looks like a reskin for mvm_underground. Pretty nice though. Hopefully we can have an interesting halloween mission this year.

This is the plot of DOOM

Don't bother making these maps. Valve is never going to update MvM.

@mykali64. In future go to the tf2 forums/discussions. Try validating integrity of game cache; go to games library, right click Team Fortress 2, press Properties, go to the Local Files tab, click Verify Integrity of Game Cache. If it doesn't work make a post on the forums (go to game library, select tf2, click 'Discussions' under the 'links' section on the right).

yeah can someone help me out here, i know its not part of this map but i need some community help here. when i start the game it says preparing to launch tf2 and nothing happens so pls help me.

НАРМАС

Nice work on the map!Some of the models of the robots could be tweaked a little and the atmosphere overall is amazing but could some improvements.All and all a great map,provides all classes with stuff they need.

mabye the robots should be scary looking or somthing like that, but nice!

@Ace★Belmont They have grown interest in it lately, fixing unessasary bugs for some random reason.

Too bad Valve doesn't give a toss about MvM anymore.

gambling's wrong and so is cheating....

cool

A MvM map? Blasphemy!
