War of Attrition
Briefing:
Autopsy of the Fell Bishop indicated that the Fell are ruled by a single entity of immense power, codename Tyrant. We must use our Etherwatt's storage with caution, as this being has great regenerative capabilities, and even stronger destructive ones.
Mission Objective:
Destroy the Fell Tyrant to eliminate the alien threat on Sagan-1.
The final stage of the Sagan-1 would take the longest time to finish. The key here is simple, build a strong patrol that would sweep the area clean, and while gradually doing so, just keep on building up the bases's defenses.
When you start the mission, collect the nearby etherium stockpiles in the area to help you speed up the defense build and recruiting. To get you ready for patrolling, you might want to recruit a Diplomat to ensure the group resilience to enemy attacks. Capture the base in the north and build up its defenses along with a shield generator.
Before progressing, you might want to change the mech to a ranger team to help you push through the numbers in the fell encampment far north. In this level, you'll notice the abundance of etherium resources. Use them as soon as you earn them by upgrading your defenses in all your bases. The reason for this is because the final boss will attack all your bases and every source of damage will greatly help diminish its outrageous HP.
The boss in this stage named Tyrant, has a pattern of attack, when it is done with the portion of the map, it will pitch in a short cutscene falshing white to the screen and desolating the entire area forcing you to regroup and fall back onto the nearby base. Markers are also show to signify its point of attack. Try your best to move your ground forces away from these points and you'll be fine. A group of 2 engineers, a flamewalker, a diplomat, and taggins should do the job just fine.
Upon beating this stage, you'll be able to unlock the next world (Ascendaar)
