my method for the last mission is to build rez up to the top of the plateaus, build 6+ blasters and 3 drones. Build a #2 bridge to the open space directly north of your city and then deploy the 3 drones to the middle (also directly north of your city) creeper spawn. Deploy the 6 blasters immediately and as soon as there is a path, link the blasters with a #2 bridge. rinse and repeat for the northeast and northwest spawns. You rely on the stored ammo of your blasters to suppress the spawns, which in turn opens up a dry area for your energy bridge. I'm currently the 4th fastest overall, but I have an obsession with building reactors (I built >40 reactors when idling last time -__-) I think if I refined this I could get a more respectable score.
I really like the concept. This is quite a stressful game for me because I get blindsided by bombs and then set back to half my height or whatever. When you pickup balloons you accelerate up and the tiny window above your house seems to shrink as the bombs come at you with even greater speed. It would be nice if there was an upgrade for a bigger grab area, or some way of reducing the terror of whizzing bombs. It also seems unfair to have bombs generated above you when you've lost 6000m and have had no leaked bombs to have bombs appearing above you even as you are falling. A reprieve after losing a lot of balloons would be nice.
This is a lot of fun; as another user said, the difficulty curve on this is really accurate.
I had to reallocate my upgrades to focus on forward lasers and shield recharge to beat lvl.10
Side lasers are my favorite though :)
Using full reproduction and infesting massive amounts of cells from the beginning of each battle, I went 24:0 with average battles of 30s. It's fun, but a little lacking. There is no rock to beat my scissors. or w/e; you get what i mean.
I've won quite handily (maybe 30 total deaths in 28 days) by using only melee and starting in Okinawa. The NPC was too passive, and it failed to capitalize on other NPC's empty barracks. It also only attacked me once.
FYI once you have 20 useless prefectures, it's fun to build Green Giant upgrades. The GGs will spawn on days 15, 30, 45 etc.
on speed 9 a piston will occasionally push two balls at a time. This is hazardous on the levels where ordering the yellow and green balls is important.
