Hi, i've just beaten Furham (S200_74), it required a lot of micro gestion though, like supplying on/off the mortar to speed up by a few seconds some generators. I was often a few second short in my actions.
Build order is collectors (as long a collector last ~40s, you should build it), generator #1, terp, wall height 7 on the bottom to save collectors (be sure to save 12 squares from bottom for the following) -you should have a only a few seconds margin to do it AND build the first generator before), generator #2 during the terp construction (be sure to stop the supplying of the terp before the end of the wall so the terp finish with 0 enerdy in stock and it speed up your gen# by a few seconds), mortar (begin it during gen #2, but play with the activate/desactivate to make your gen the priority), generator #3, mortar #2, wall heigth 8, and possibly 9 on your launchpad if the mortar is a few seconds short from completion
Then you need to build generators ASAP while using enough mortars to not be overflowed. Then ~40s before first spores comes, you build 2 beams (at which point you should have if i remember 3/4 mortars).Be sure to micromanage mortar supply to speed up generators construction.
You reach stability @6 mortars and 5 beam towers
You then need to pump your def to 4/5 mortars and at least 4 beams and have enough energy to keep it up.
