The author described his approach as "rediculously simple", and I'm inclined to agree, saving the "rediculous" part, and that only because it seems to portend something negative to this map.
The offense will start in a sealed off base.. no cheap attacking for the defence! A quick ski down a hill, and there's the objective.. two of the Katabatic outposts merged side-by-side. One generator is in one tower.. one is in the other, and the switch sits by itself. How much more simple can you get?
And yet, once the goings-on get going on, you realize there's more than meets the eye. The battles outside are open and spacious, with nothing in the way.. and the fights indoors are cramped and claustrophobic, with nowhere to hide. It's this very difference, stark and clear-cut as it is that provides such an appeal for the map. Switching from one fighting style to the other strains one's skills, and introduces a set of fast-changing objectives. Even the generator placements encourage a strange mix of long-range close-quarter fighting.. just enough distance that you can, if you're careful, not be hurt by your weapon radius.. yet for sure close-quarters, for your enemy has to walk but a few steps and he's by your side.
Playability really becomes hard when the defense gets entrenched. With spider turrets and heavy guards, the firefights inside get more and more difficult for the offense. This, of course, just requires the offense to strike fast in order to combat.
Attention to Detail I found not to be lacking in any way. The base alignment and positioning, plus the location of the offensive base all speak to the thought behind creation.
Balance is, as mentioned, a heavy slant to the defense. Give them a few moments of peace to set up, and they've all but got it made unless the offense is elite, or the defense is just purely incompetent.
Item Placement is a little off, because I quite simply couldn't find an inventory station.. now, that could be because I'm stupid, but I honestly couldn't find one for the longest time. Even so, I was able to do fairly competent battle with the liberally scattered powerups all over the base.
The Mechanics of the map are awesome.. I love the way everything comes together in one huge free-for-all indoors, then culminates with a mad dash to the final switch, while the defense frantically tries to repair generators and the offense holds them down, buying time. It's great!
Final analysis: Give it a go! Fast-paced and filled with an adrenaline rush that just won't go away, I enjoyed every moment of it. (Save the part where I felt like an idiot while looking for the inventory..) Play it! Love it.. Own the enemy.
