This is a very nice map ! I like the lighting and the layout, too. But i have to agree with Drakas, some spots (top) are hard to reach, and it would be nice to get back up to the top (from the bottom) with an additional jumppad. Also there is not enough rifle ammo imo ;)
Also agree with the floating cubes - either they should be placed way higher, or even delete them, they are just obstacles when moving around.
Did you think about adding some more details to the plain walls ? Would look good imo.
All in all i can say, this is a very nice map (your best so far) !
I´ll give you 3/5 atm, will rate higher when you´ve updated it...
Good job, please keep it up, c u :)
