This is how I started it off:

http://gtm.you1.cn/sharedfiles/filedetails/?id=517810620

Had the science lab zap everything and AT bunker deal the bulk of damage. Drones + Spec Ops + Shotgun sentinels to help out. By the late stages I had more Spec Ops there, though since the updates, I am not sure how well they'd fare against the boss. When the boss comes in, I put a couple of Gauss Towers there too, since they do nice damage to him.

A problem with this level is that it is easy all the way until the final boss, and then it feels impossible.
This means having to play a lot of stuff over and over, just to experiment with how to kill that final boss.
What kills that final boss? Troopers, anti-armour and spec-ops, apparently.

[Edit: All right, I killed it. :)]
First, max out 2 science labs and the gun already on the map.
Then start creating spec-ops marines only, every time with all their upgrades (especially cloaking and disruptor grenades).
Then when the boss arrives, make sure to move their flags to near where the boss is.
And also destroy spec-ops where the boss passed to make sure you can build new ones further down the path.

i use only tech turret easy win and laser turret

Author of the post asked about Swamp VI and shared screen of this level. But you shared your strategy about another level.

But yeah, its mistake from devs because they named wrong name to the level. This level must be named like Swamp IV, not Swamp VI.

Swamp 6 bug or superstrategy!?

My boss somehow got trapped in this combo of towers. It couldnt get really past the troops and drones and got hammered by the laser and lab ...

Hope this helps somebody
