I finished off Darwinia this morning, and it didn’t take as long as expected, though I did know that the Escort mission was going to be short. The remaining enemies were no threat, and although I only had to save 100 Darwinians, I wound up with 505 at the end.
The Temple level was then the final one, where I had to destroy boxes representing the spam emails that had the virus that corrupted the system in the first place. They complicated matters by sending out tendrils that would respawn enemies even on other islands, so that no area was completely safe.
But, it actually turned out to be a fairly easy level. The boxes were all fairly close to beam drop-off points, so I just rushed in some squads and dropped airstrike markers by the boxes, which were enough to destroy them. Presto, level completed in no time. I still went ahead and mopped up the remaining enemies scattered all over the place though, just to make it less anticlimactic.
And so ends Darwinia. Despite the rather easy win, it was still an interesting game in that every level introduced something new and unexpected, so it was never really boring. Beating it unlocked a level editor, but I don’t really have time to fiddle with it.
