Montstr. Your office. Your team. Monsters.
A game based on your workplace. Your colleagues become playable characters, and zombies storm the office.
How it works
Plan
A photo of the evacuation plan, a floor drawing or a hand sketch, plus 3–5 places people know the office by.
the demo office plan Characters
A name or nickname, a look and 1–2 signature details for each. Only those who are up for it get in.
Mary: slim, red hair, glasses, never seen without her yellow scarf

Three classes that set how a character plays: agile, balanced and powerful. You decide who gets which. Or we take a guess.

Everything is fair game
You survive using whatever is at hand. And the surroundings.

Appliances
The fire inspector disapproves. Careless handling leads to disastrous consequences.

Server room
Where the web comes from. And the spiders.
Asset No. 000508
Windows
Unreliable: may crash. Sometimes taking the user with it.
Asset No. 000101
Fire extinguisher
The fire inspector approves. Puts out any fire — except the ones in your inbox.

Workstation
Keyboard, monitor, mug — you can grab them. Other people’s: survival use only.
Censorship
Two settings, three levels each. The order sets how spicy it gets; in the game it can only go milder. Pick what suits your company — we can also add your favorite expressions.
Blood
Office
default
Paper, sticky notes and confetti fly. Heads stay on.
Zombie
on request
Green blood for the zombies, paper for the players.
Adult
if you wish
Red blood; heads don't always stay on.
Captions
Mild
on request
Nothing rude.
Too slow!Not so fast!Normal

Return to sender!Per my last email!Strong
if you want it and you're 18+
With swearing. Bleeped out here.
Nice try, !Back the off!
You can also switch captions off and do the commentary yourself. The demo on this site has no blood and no swearing.
Game modes
Deadline
A four-minute run. You start empty-handed: weapons are found around the level, and they break. The goal is to survive — efficiently and spectacularly.
We'll adapt the mode's name and texts to your line of work: IT, construction, accounting and so on.
In progress
Tutorial
Writing the training manual.
Infection
We're working on it.
Survival
Endless waves.
