Hi there everyone.
My name is Jake and together with my friend Chuck (aka Nubcake)we created a map called tremship.
It has been very popular on Aussie Assault, and we are even working on specific versions for Z server, and have had unconfirmed reports that kor plays it.
Explanation of the map is below, it was made for Aussie server with around 25 people, but if any other servers would like to play it and need some changes to cope with larger numbers please let me know and ill be happy to help

It is a map loosly based around the Starship Troopers theme where humans defend against hordes of aliens.
The map itself differs from normal play in that it is purely a survival match on the humans behalf. I will explain.
They humans start with several hundred build points worth of defence behind a barricade wall.
The goal is for humans to defend there outpost for a full 25 minutes after the first member is spawned. their base is quite large and 2 armouries are invulnerable. However their turrets nodes etc are not, and once a building dies, it cannot be replaced.
On the other hand aliens start with eggs which the humans cannot kill, they also get a booster from the start. The humans cannot use helmets, battlesuits or the jetpack which means they need their turrets and Tesla's to survive.
At the start aliens will be dretch rushing through tunnels and over mountains. As the aliens gain evos the humans will start to lose parts of their base from goons etc. It is very important for the humans to try not to feed!
If humans have managed to survive to the 25 minute mark it gets interesting.A bomber will fly over the map and kill the aliens eggs, a few seconds later a the bomber/shuttle will fly down in front of the humans base wait for a minute then fly to the mothership in orbit.
The aliens at this point can choose to stop the humans getting on the shuttle, or run off. and the humans can just rush until they are on the transport and taken to space. Where they nuke the planet killing all aliens and winning the game.
After 3 trial versions, we genrally find this map lasts between 18 minutes to 27 which is why the bomber comes at 25, to give the humans a fighting chance.
I should probably add that the whole idea of this map is just a high kills game and instant action that wont stop because a team is afraid to come out - alien feeding means absolutly nothing!
