I made this little map on Eden 1. Modified to avoid enemies spawning on cliffs and widened the spawn area for a longer game.
Initially I made it as a test map for some functions I wanted to make, but with obstacles hindering any progress, I went with doing some bla and the result is this little piece.
You basically get spammed by generated attack waves starting from mark 666. There are some difficulty settings, but as I didn't take much time to balance, be prepared for it to be too easy or too hard or simply weird.
Once it gets to Tiger level, the number of attackers steadily increases with each wave
I used survtechm.txt, albeit modified a bit, which is included. This is very similar to the survtech we all know and love, but I went and added some devilish things you shall have to find out for yourself, as well as some boons, which... you shall have to find out for yourself.
So... Enjoy?
EDIT: I keep fiddling with the numbers, trying to balance it here and there. Be prepared for new versions popping up from time to time.
EDIT 2:here's little left to be changed if no one plays it so I can do balancing.
EDIT 3:Altered the AI some. Made it slightly smarter, so to speak. Also altered wave intervals. They are now difficulty-dependent as well.
Disasters are open for request, although they're slightly pointless on such a small map.
