Here is a map I've made, it's made for fast pace game play. I'm guessing it will be fast like egg&bacon.

It is a really simple map.

The water:
I'm going to keep the water like that so it's like a hiding place.

Enjoy.

cool. I've got a few suggestions:

Maybe a ladder to the roof here? (perhaps a hole in the room to the water too)

100 health / armor on opposite corners of the bases

Yeah, all good suggestions, I will start working on them now.

Have fun!

If there are any issues please tell me, I haven't had much time to test it yet.
