Custom Map #28: Bertha

[NickLucas]

Is there a video for this map anywhere ? I've completed all the others in this series but can't get going on this one. I've completed a 3 high wall around 4 beams a couple of times but then the creeper comes over the wall ! Any help gratefully received.

The secure (slow) way:

Spoiler

Place 3 CN near the top (or bottom, but let's say top.)
Build some Collectors down the map, and then switch to a Reactor farm.
I don't recall how many you need, so expand where possible.
Add Mortars on the bottom and right, and Pulse Cannons on the bottom.
Add Beams.
Add more Reactors until you have power to expand.
Work your way down to ~1/3-1/2 way down the side, then jump the wall at the top edge.
Keep going, remembering that the power drain of weapons largely depends on the size of the front.
So, corners are cheaper than edges, and an entire side is cheaper than 80% of it.
Push right.
(I think you can guess what comes next.)

It is possible to rush the bertha tech, it may help to keep the creeper down.
After the forge is built and you have the energy efficiency tech, you can build out much faster and power far more mortars, so build a forge as soon as you can afford it.

Spoiler

Once you've got some spare energy, use berthas and guppies to take out the spore towers and then work your way left, that's much easier than pushing right.

Many thanks guys. The screenshot shows the initial setup I ended up with. It takes a lot of patience but it works !! I finally beat all levels. Thank you J for a very interesting challenge.

Ouch. I don't envy you expending from there.

I agree it's a good series. (I wouldn't play again, though.)

I was a bit surprised to see this map all the way up in the front page when I checked today.
