Here's the first map for Onslaught minigame:
Snow Town!
Description:
You start with a knife and a bit of cash. You have 30 seconds to buy what you need, then the onslaught begins! Zombies will come at you from all angles, non stop with varying speeds and aggression. No upgrades. Just guns, your knife and your ammo.
Last as long as you possibly can, the zombies don't ever stop coming...
Tech notes:
Including this in the first build for fun. Rebuilding now and uploading to Steam. This is not a complete map or mode yet. We're testing procedural level design for this mode, meaning every time you pop into an Onslaught map, it won't ever be exactly the same. Testing this means things may not always spawn where they should yet. But at least there are some hilarious results at times :)
Enjoy!
