Tonight I finished off two more levels in Darwinia. In Pattern Buffer, I encountered evil red Darwinians for the first time, and I was not prepared for them as they flooded out of portals in waves. I hadn’t used Armor much in the previous levels, but it was essential here for keeping the red ones away from my spawning areas and mission objectives (they’d try to take back stations that I parked my own green Darwinians at).
And in the Biosphere level I had to take over a whole bunch of Darwinian generators, which started off under the control of the red ones. Armor proved useful here too, but the Darwinians themselves were also key to controlling areas. The generators were on a bunch of different islands, so I’d have to clear out a generator or two with some squads to establish a beachhead, park some Armor near them to keep the other red ones on the island from taking them back, take control of the generators with green ones, generate a bunch of other green ones, and then use squads to cover them as I swarmed the rest of the generators on the island.
I also started the Escort mission, but didn’t have time to finish it. It doesn’t look too tough, though; it’s just a bunch of clearing out, and the only annoying part was a bunch of hard-to-reach seed launchers. I snuck around and eliminated those, and the rest will be trivial. (I suspect that I wasn’t really meant to take out the launchers, so that I would have had to escort the Darwinians through the level while still fending off enemies spawned by the seeds.)
After that I think there’s only one level left, Temple.
