Total Annihilation/Xantippe's Abyss

Mission Briefing
Intell-tap Arm has assembled an Annihilator weapon on the other side of Xantippe's Abyss. The one crossing is well guarded. Capture the Bertha Cannon to the east and use it to weaken the

Arm defenses sufficiently to destroy the Annihilator.

Expect meteor showers.

''Capture an Arm Bertha. Destroy the Arm Annihilator.''

DO SO NOW

Details
Starting units: Commander

Head east to find two Sentinels and the Bertha. The Bertha won't fire upon the Commander, but the Sentinels will, so take them out quickly. Capture the Bertha and find some Dragon's Teeth nearby for a good early source of metal.

You won't need any significant defense (none at all if everything goes right), you just need the Bertha and an Advanced Radar Tower. Build south of the Bertha to be safe, going through the tree to get an Advanced Construction KBot to build the tower. Placing the tower just north of your position should expose the enemy units quite nicely, which will allow you to pick them off with the Bertha.

To get through the tech tree, simply build the KBot Lab, Construction KBot, Advanced KBot Lab, and Advanced Construction KBot. You may also wish to build an Aircraft Lab to put out scouts that will help you pinpoint the targets of interest.
