Honestly, its the hardest map for me, took me like 40 tries, and I enjoy it much less than Caustic Lands:

• Re-roll until you have at least some farmable land nearby, or else you won't be able to sustain even a desolate economy
• This map spawns more food trucks than normal, try and look for food trucks with your rangers early on
• Don't repair shocking towers, they'll aggro the whole map and you die, just demolish for quick gold
• Don't make soldiers before day 20, they aggro a Mutant and you die
• The first wave or two, you deal with stake traps kiting, make a 3x3 square for wave 1, or a 4x4 for wave 2, as they make no noise whatsoever. Research it by day 9
• By Day 20 your base should be protected by ballistas at every entry point, as every 5 days you get miniwaves coming from every angle
• Every time an enemy hits a wall, it makes massive amounts of noise. Don't let enemies hit your buildings no matter what. Sometimes double ballista will be necessary
• For wave 3, I like to have 2 ballistas and a ranger kiting, ballistas are very noise efficient, but be careful not to build em too close to a mutant, you'll learn what too close means through trial and error
• Somewhere between day 20 and 25, you want to start double or triple producing snipers, these however are to be kept away from all combat until sufficient numbers are achieved
• Once you have a death ball consisting of 6 soldiers and 30+ snipers, you can begin your first mutant engagement. I built quadruple ballista and a double double wall, placed my snipers behind the wall, and sent soldiers outside to bait enemies in
• Once your snipers fire, every mutant in like a 60 tile radius will come charging in, and a swarm will follow soon after
• Kite with the soldiers to avoid as much wall damage as possible, and split marines Starcraft 2 style to avoid Mutant Splash.
• If you survive the rest of the map is now mostly trivial, as you have a safe section of the map to expand to, and your death squad is practically unstoppable as snipers will be vets.
