Kill Them All
Author: Azrael

Everyone starts with a Defiler, and you use dark swarm to teleport and plague to kill. Not much else to it, but the simple gameplay is intuitive and fun. Made in 5 minutes.

Stomp The Fundies
Author: Dem0n

Defend atheism and science by destroying all the fundie oppressionists using four atheistic heroes (Carl Sagan, Neil DeGrasse Tyson, Richard Dawkins, and Bill Nye), and prevail by defeating notable SEN fundies in a boss fight and the final boss, Pope Francis. Win by burning down the church. Plays like a hack and slash RPG but without the RPG.

Creep Shots
Author: lil-Inferno

A silly experimental map. You are a creep with a camera, and you score points by taking pictures of small children and young adults. Taking pictures of old people causes you to lose points. If people are near you when you take the picture you will gain notoriety, which will cause the police to come after you. If you die you lose all your points. Whoever has the most points by the end wins.

Hotkey Hotkey Revolution
Author: Roy

Hotkey four units (representing the numbers 1, 2, 3, and 4) and hit those keys in correspondence to a Dance Dance Revolution-esque pattern of units that come down, when those units are on a certain point of your playing field. The player who misses the least wins.

1hmap

To be honest I have no idea what this is, because when we played it, it bugged out.

Pterodactyl Game
Author: FoxWolf1

Grow up as a young pterodactyl into a bigger pterodactyl capable of defending itself while avoiding smoke clouds (Overlords) and high ground (which kills). When you grow up, defeat all of the other pterodactyls using your abilities to claim victory.

1hourmap
Author: Chia-Tyrant

Very incomplete and buggy, but an interesting concept. It plays like a choose your own text-based adventure, but using a vote-based system rather than one user dictating everything. Spoiler: No matter what you do, it'll end with your death.

tomkazansky
Author: Cinolt (aka yoonkwun)

Everyone plays as Tom Kazansky (Wraith) and must get 5 kills to win. If you stop moving, you will die, so you must get hits while still moving. Since it takes two hits to kill someone, you can just suicide after getting hit once to prevent someone else from getting a point which is the map's most fundamental flaw.
