Jumping oh fun!!! Thats what I can tell you about Q3ATest2 map
sure it's not everything. Here is my help:

Use Railgun for sniping from its place only if you are standing near the jump-back pad
To get someone down from the Quad Place use Railgun Sniping or Rocket Launcher
(fire on the Platform not on him) don't jump there , he can kill you 3x faster.
Jump-move-jump-move...
If you can get the megahealth , it gives you realy good advantage of better health.
Try Rocket Jumping - use the shockwave of any explosion to jump or move faster.
Don't look down when landing you will take additional damage for bad landing.
If anyone is in the air try to push him out from the map (machinegun,railgun{rockets
are too slow but sometimes...}shotgun on short distance is really powerfull)
If there is a Sniper : hide, crouch, shoot rockets, move fast, dodge and bluff
(good sniper hits you every time you jump).
If you are in a really bad situation (means low health,ammo,armor) try this
(I call it the way to heavens)
Get the nearest gun , use the nearest teleport , take the armor jump on the nearest
jump-pad from the group of them in the middle of the base then the middle one ,
take the megahealth jump on the next one and fly to the quad walk through the teleport
jump to the next JP and get the Railgun
If there is no Railgun.....................don't jump there.
If there is no Quad........................don't jump there.
If there is no Megahealth...............don't jump there.
If there is no Armor.......................go without it.
If there is no Gun...........................go without it.
If there are three of them missing...don't go.
(only acceptable combination of two things is:
Railgun+Megahealth)


Happy Fraging to you and bye bye.
