Surviving Mars

Still very easy to get after patch (as of 9 May 2019). Simply select SpaceY as your sponsor. Load your first rocket with max number of drones (20) and drone hubs (6).

As soon as you land, deploy the 6 drone hubs. Each one gives 8 more drones. It doesn't matter if they aren't powered.

Then request more rockets with the same shipment (20 drones and 6 drone hubs). You should soon unlock the achievement.

Thanks to Fuzzy Bear Hugs and Daft Incarnate for their solutions and the inspiration.

This achievement is suspiciously easy to obtain (as of 16 April 2018). I highly suspect it'll be patched eventually.

Start a new game and select "SpaceY" as your sponsor. Commander profile doesn't matter. Neither does landing location.

In your first rocket, remove all the preset cargo. Fill with 50 drones. Start the map, and immediately hit and go to Resupply. Fill 3 more rockets up with 50 drones each. You will have just enough money to do this: $6000M starting funding / $30 M per drone = 200 drones.

Simply land all 4 rockets to win the achievement.

Sadly, it's been patched. If there are physical copies of the game, you could do a fresh install and cheese it. But, Daft Incarnate's method is solid and I highly recommend you check out their guide. Good luck!

There are 3 ways you can acquire drones for this.

Building a new drone hub then dismantling it. A Drone hub requires 12 metal, 8 electronics, and 3 power. With the research that adds 2 drones to a hub that makes 12 drones added for 8 electronics spent. There is no half cost return for dismantling drone hubs, but at least you aren't using additional power. SpaceY has reduced cost electronics so this is definitely the quickest and easiest method if you're importing electronics, but consumes metals quite quickly.

A Drone Assembler can create a Drone for 1 electronics, also requires 1 electronics for maintenence every couple of sols, but can be relatively quick when staffed by 12 engineer colonists. There is a breakthrough research that allows them to be constructed using metal instead of electronics, if you have that I would recommend this method.

Alternatively buy 5 drone hubs prefabs for delivery for $750 total, thats 50 drone (or 60 drones if you have the additional drone research). Viable option if you research Martian Patents (500 for 3000 research) over and over and don't have metal to spare. That's 3.33 drone hubs for every completed Martian Patents. Obviously requires good research rate and fuel supply to send rockets back.
