Ouhhhh just finished Miner Evacuation with all bonus objectives completed and completed the game without much of a hiccup other than my mistakenly launched nuke.
My partner was using Karax, a very capable one.
Objective 1 (center) - together, happens to be near expansion so we cleared that.
Objective 2 (left) - I go alone (Nova) with tanks and mines. Before the ship go into lift-off mode I head over to blight with Nova, Marines and Goliaths. Once done, head back to defend.
Objective 3 (lower right) - I go in alone (he's spamming cannon at expansion). Defend against wave, but this time whole fleet go for Eradicators. Lost a lot of units there (left with 1 Goliath and 3 ST) and flight back to defense point. Enemy was minimal because I think the fella did damn good cannon placements and support.
Objective 4 (upper left) - I go in with my units replacement coming in. By now I start to expand since it's already secured. Stopped the attackers from reaching, clear the path.
I secured the center while right side is massive cannon spam. He's got good income already by now as he expanded.
Objective 5 (upper right) - Partner stopped incoming threat with beam, then I fly over to nearest point to clear the area. After that his probes came along to spam cannons just ahead of my ST group.
WIN! 0 shuttle loss. 2 objectives completed.
So hard to come by excellent players like this.
