The atlantic accelerator is a cakewalk.
Take 4 fully v3 cyborgs. Equip each with 4 energy sheilds, 2 gauss guns and 2 flamers.
When the level starts, immediately go into team mode, activate the sheilds and turn the drug bars (adrenaline, perception etc) to minimum.
Go out of team mode and move agens 2-4 a few paces away from agent 1.
The enemy ai is predictable in that they *always* go for youre least armed agent first or if all are euqally armed in numerically ascending order.
The trick here is that you can use the flamer which never injures an enemy it always kills them outright.
Simply stand there whilst several waves of bad guys pile onto your position. Eventually theyre all stood right on top of agent 1 and stop firing and there will be relative calm.
Take agent 2, activate a flamer and simple roast the spot where agent 1 stands. About 20 burning enemy agents will erupt from his position.
Leave agent 1 where he is. All the active enemy agents will still be trying to reach him but can't navigate properly so end up goin in circles. They'll ignore your other guys.
Take agents 2-4 and put them on corners where the active agents are always running past and toast them with the flamer. Eventually you'll kill them all and they won't even fire a shot at you.
There are 2 agents running around inside buildings. You can stand in the doorway and flame them.
Use your guass guns on the tower guys, making sure you do so from a big enough distance that they don't see you.
Et voila. Mission Completed :-)
Also, the long range rocks. 4 v3 cbyorgs with 8 long range rifles a piece in team mode (with panic mode enabled) are more than a match for any enemy cyborg. I use that trick regular. There's nothing like that rapid tattoo of gunfire it produces :-)
