I did this three times and it was nearly impossible for me to connect the southern totem.
I placed Odin City on the ridge by the emitter pool, used 1 blaster to block off the eastern emiter by 1 of the toteams, and used two (then 3) blasters to move forward.
Deficit kept destroying the collector because it wouldn't even finish building.
This one?
I had the weirdest sens of déjà vu playing that map.
I said 22, not 23.
Oh well, that one is slightly easier....
I believe March 23, 2012 is similar to Sculptor the story map to you Grauniad
So I found a cool challenging map.
August 27 1507
I don't have any uploaded images but a pinned myself down in the corner with 2 blasters and spent a few minutes until I could build some more blasters and expand to build more reactors and blasters. I'm pretty sure you need a Drone bomber when pinned down so the creeper doesn't overwhelm you.
This was a pretty fun map. Good luck you'll need it ;)
On the map the day after (the one graunidad posted a screenshot of) a person had a score of 1164 minutes!!!
I enjoyed a return to CW1 - the southern totem on the 22nd map was accessible by flying the ship over the token and bridging it with a SAM or something else cheap to build, as opposed to clearing the creeper out of that level. Obviously there are quicker ways than what I used, based on the scores.
This puzzle is solved with the best score without ammo packet: one SAM, two upgrades and eight collectors (or one upgrade and six collectors - I don't remember, how was quicker).
