Haestrom, Thermonuclear Insanity Challenge (more like Hardcore, since I have 5 Waves Survived)

I was sooo bummed out too! I made It all the way to Wave 10, only to have a Combat Drone Stagger me so I couldn't side step around the corner fast enough or use an Ops Pack. A Geth Rocket Trooper brought my shields down, and the Geth Prime took me out! >.<
All I was trying to do was get a good angle on the target, which was another Geth Prime as my first missile failed to switch targets. I used my last remaining missile on it along it with a Geth Rocket Trooper, and it still failed to switch targets. So I ended up dealing with the last 2 Geth Primes normally. I extracted without using another Medigel though and had 1 remaining Ops Pack.

Wave 3, Targets. I used a missile on the Geth Prime and Geth Pyros and it switched targets to the Geth Pyro.
Wave 6, Devices. Really easy, the first one was at the LZ and the three remaining were on the other side of the map. I did the last 3 without disturbance . lol
Wave 10, Targets.

Wave 9, I used a missile at the start of the wave because a Geth Prime and two Geth Rocket Troopers spawned behind me unexpectedly. then another when all them were together for a killstreak. and one more for the last Geth Primes to save on time.
I was using GriM's build. 6/6/6/6/0
