well, first off all, very good you're making an assault map that's nice, and i can't agree more with the people already saying that the map tend to be confusing...
well the start is a bit dark, can be fixed fast, so don't worry about that.. and fps drops to 8 here when i go the route with the invisebilety... that's just to low, oh and invisebilety has nothing to do with assault, as you can sneak to the objectives... so i would say to remove it.
you've builded the first autocannon that i kinda like, it's not very powerfull and easy to avoid, so that's good
that yellow thingy before the normal door is kinda useless because (as iwer pointed out) players can hammerjump and rocketlaunch all over the place... and because that first run, (to the destroyeble wall) is kinda long, everybody is going to hammer over that yellow thing, however def can snipe them down all over the first run, so this will be a pain in the arse to concour.. this can be done by a double hammerjump, so people wil fly to the side entrance, but when they reached that wall, and destroyed it they will get 2 or 3 shockcombo's in the arse....
but because you can launch you can get (for instance with some practice) to those crosses where the jumpads are) and when you reached that point, defence is unable to get you because they spam in the main castle,.. maybe you should make a little room with some teleporters to some parts of the map, that makes it easier to define where you are and defence can defend lauches
your messages, are tried to be leet, but are more anoying, i mean, they cover my whole screen
chain 1 is destroyed is good enough
that way (where the spider is) is easily spamed by 1 (or 2) persons, you will find it impoible to get trough. can be used as a sneaky way, but not as mainroute, like bots do, because you will get spammed
because the castle is 1 big room (kinda) some mid objectives will gain undefendeble status, as attackers can run all over the map
what SX means i fink, is that when you hit the jumppad you are in 0.00000001 second 100 meters in the air, it feels like you teleport into the air instead of jump...
and what about the ammo, i mean, there is so fucking loads of it, people will only use the good weapons, e.a. sniper, shock rocket and sniper, because they have enough ammo...
that's what i found for now, lightning needs to be better, and same goes for fps, but overall it looks, good, and original.
keep up the good work
