I've just tested 3 maps in Editor mode: "UFO" and "Beasts of Freninj" by saxc, and "Pools of Blood" by C_H_E_R_U_B1-1.
My reviews:
First of all,
Beasts of Freninj looks amazing!

The fact that you can go inside that "monster" makes it even better! This map is
very good for stealth campaigns or sniping, but its also good for close combat, especially when you're inside the monster and going to
attack snipers who might be lurking there, or when you're throwing a grenade from above into the interior, so the enemies below you
get blasted to death. lol.
UFO also looks very good; it's built highly accurate. Nice detail work!
It seemed to be good for sniping firstly, but it is better for mid-range shooting and stealth attacks i think. The tunnel system
(nice idea btw) can be used for sneaking into the enemy base i think.
Pools Of BloodA cool idea! You've put very much effort in it, C_H_E_R_U_B1-1!
I think it looks very good, but a bit unfinished in some of the areas. Some more detail objects, then it will be perfect!
This map is a 100% close combat map. Commando or Guerilla weapon set highly recommended.
Apart from that, i've detected two bugs:
-There's a platform in the middle of the pool, but you can't get on it. That means you can't play "Uprising" yet. Lower the platform.
-While heading for the UFLL base, i came up against a block, which was too low, so i had to crouch to get through. When i
was going back to the pool, the block was invisible, so i came up against for the second time. 1. Lift the block. 2. Fix the invisible-block-bug
by covering that spot with another block.
