I just tried the level out. Not bad. It's not as big as the original facing worlds, but it's definitely playable. It's on the small side as the distance to cover is smaller so the sniper rifle isn't anywhere near as useful as in the original facing worlds map. However, I did notice there's three areas. The middle which is where you spawn and run onto the enemies area, the higher area of the tower where you get the sniper rifle and aim at people though, it's nowhere near as effective unless you're a very quick shot due to the lack of distance, and a bottom floor which has some more weapons and is a quick way to play keep away as you can use the teleporter to go down there and wait for enemies to come or just hide while holding the flag.
I also noticed that you can enter from three points. The middle which has the most space obviously but can probably be choked off, but you can nudge from the left or right as there's enough space for one person. The map is small enough to actually have a decent game with 2v2 and can go as high as 5v5, though anything more then that would be too hectic due to the size of the map.
