interesting map, its reminding me to chronos (even tough chronos used more variable lights) :D!
overall the map looks a bit (a bit??? :P) like thoes of quakelive, open arena or halo of half life 2 :P.
the maps seems to got not bad lightning, but u should add another bit more different lights in it. the detailing is nice, i like that blue light u used 2 get a nice pointy sting. replacing teleport for default, isnt original but good :D!
The texturing is pretty much repeated, what makes it kinda boring, u should try to add a bit more textures in it, what gives a more "intense" gameplay. Not a bad option to, to trim the edges of those long narrows ways to both bases.
The gameplay, the flow doesnt seems to be bad, only those much teleports and jumppads makes it pretty difficult to beat the flagholder of opponent's team down when ur chasin him (not camping! :P). u just should make the gameplay a bit more easier, so u still can follow movements of players. from the other side, cause of those not-easy-to-follow-movements camping doesnt gets easier.
1 Big problem this map got: pickups. u should add way less pickups (u wanna play this map with 30 people or sumthing??? :P). its not necassery to put so much pickups in this kinda map (even tough i know its ment to be u can frag each other easier). after all it still has 2 be a bit of a challenge 2 get some pickups and frag ur enemy with it.
So, put the pickups on less big numbers and paste them on "challenging" places, like that u have to jump to get them or moving from u target away (not recommented to paste them in places were u die if u took a misstep when taking a pickup).
anyways nice map! i give 69/70 points for now (so rounded down =s), if u would do something (about the map) with the comments that r getting posted, then u probably score up to 100 points :D!
