Goblin Defenders Level 8 Borderlands hard 3 stars annotated

PC version of the game Goblin Defenders: Steel 'n' Wood. This was an incredibly tough level to get 3 stars on hard difficulty for me! I got all the achievements for staying alive with just 1 heart for 10 waves on this level. There isn't much cash to spare. But eventually I figured out how to build a good maze and just about keep the air units back. I'd advise playing all the air waves at slow speed to give you time for upgrades. I didn't always because I was trying to make the video shorter. I tried a similar strategy on the Survival version of this level, which is actually easier. I made 54 waves. I was able to build up extra cash, and so able to replace all the crossbows with monster Teslas eventually (adding a few extra cannon to compensate for Electrons). But in the Campaign version of the level, you don't seem to have a lot of spare cash. However, it might be worth adding a monster Tesla or two every time you get a sheep bonus level (replacing the crossbows).
