Revivefarming
The Challenge-System was teasing me with only 5 waves on Hydra left to get the 100 Waves done for Bronze, Silver and Gold. So I called the BatSol to duty, equipped the Talon with HB and poweramp, With Grenade Gear, AP IV, Cyclonics IV and Pistol Amp III nothing could go wrong...
I searched for the map, got a lobby with two noobs (<1000CP) with some mid-level weapons. Both had selected power-dependent kits, Shadow and Merc, so this looked good. After me a volus joined, we readyed up and got Reapers.
The Volus was afk or glitched out from start, and the other two went ramboing and got stomped in wave 1. And in wave 2. Wave 3 was devices, I did them and clutched the wave. Starting with wave 4 - I really hate soloing - I was basically running in circles around the map, reviving both pugs, grabbing grenades and spamming them and blades left and right, while shotting down Mooks and Banshee-Barriers with the Talon. Worked surprisingly well.
Wave 6 was hack at the LZ. Pugs were running all over the map, with me yelling over the mic at them to stay in the circle. Host kept dying on the other side of the map, and told me he only understands russian. Oh nice, my last lessons where 32 years back. At least the Shadow got it. I used 2 nukes and gels. Had to clutch two more waves. Pugs got grabbed by Banshees or got stomped before I got there. And headshotting Marauders across the map with the Talon is...problematic.
Wave 10 devices. Did 2 of 3 while reviving the "team" like 20 times. Last device was the center one 
I tried till I only had one gel and nuke left. Kiting didn´t work because of the pugs. So I was yelling again, this time at the shadow, to cloak and get the f.... thing done. No luck. To my surprise, the Merc grasped the problem and did the device, while i was meatshielding him and nuked the approaching Banshee.
And in the end we got even a partial extraction. Yeah...
Maybe I should consider to do the solo-challenge after all? It could not be worse.
But I hate soloing...
