Since we launched the Map Editor, lots of people have already made some great maps so we thought it might be nice to award a great prize to one of the best.
The prize? A Steam key that will give access to all current and future Mastertronic releases.
To win, post an image of your map on Twitter using the hashtag #over9000zombies by the end of Saturday 8th November.
If you are not the twitter type, then please just post a link to your map on the Workshop in this announcement thread.
Happy creating and good luck!
