I just did The Hive solo with Robotics Expert.
I had early Imagoes and the Sniper. I was able to stealth them for their guns. I then went to the ammo room on the right (need all I can get) and there were two Drones and a Sniper there. Was able to kill the Sniper with Boltok and one of the Drones with Longshot. The other one was unaware of his friends getting shot so I could just meatshield him. The Grenadier and the 4ish drones in the area before the pair of ammo rooms (after the many Rejects) were unaware of my presence so I just meatshielded them all.
The Juvies by the rooms were killed with the Incendiary and melee (not risking anything.) Once I was at the big room (this is a tough area) I sniped the two Drones I could see (there was a Grenadier too) and then tried to get the others. What sucks is they don’t like showing up until all of China knows where you are so sniping them is harder. I got a couple but I ended up popping my ult since there were still so many left. The DR-1 was able to kill the Scion and the remaining Drones while I ran away.
Got the Elite Grenadier and the Mulcher Scion (way, way better than the 15 Juvies and Elite Grenadier spawn.) I threw a flash at the Scion as he turned the corner and then just used the Enforcer on him. It took 80 shots to kill him and two flashes. Luckily, either I could maybe get one from the Elite Grenadier that was with him or from the last two supply rooms. I ended up killing him with the Mulcher and he actually dropped a flash (yay!)
I went right since it is a lot safer (just several Drones and Elite Snipers (which have EMBARs, which I want. Other side has Sires, Drones and Elite Grenadiers and the ammo in there isn’t worth it.) These Drones like to be aggressive so I only had to snipe one. The other Drones I killed with either Enforcer or Boltok. Snipers got meatshielded. One side rolled and the other didn’t get stunned but luckily, I saw it coming so I rolled back and hit him again. The EMBARs had 5 and 4 shots in them (not very good RNG)
I heard the Flock but I think it went around to where I was before attacking the Drones. I decided to ignore it since on several past attempts, it just would stay in one spot so I could ignore it. I sniped the Imago and the Drone on the far right first (they can be troublesome) and then tried to hit some Snipers. I killed the Mulcher with two Longshot Headshots and the bleed did the rest. Elite Grenadiers got meatshielded except for one which got EMBARed since he was being nonaggressive. After shooting some more Drones and Snipers, I went to the upper left to try to get a better shot on the Dropshot Scion but he went to the area which you first enter the room and an Imago snuck up on me from nowhere but I was able to hit him in the head with a Boltok shot and then melee him before backing away. I EMBAR stunned the Scion and let the bleed kill him. There was a straggler Drone before heading to the helipad so he got EMBARed.
Once I made it to the helipad, I had about a dozen Juvies and an Elite Grenadier. I threw flashes at the Juvies and then popped the DR-1. The DR-1 took care of the Juvies and let me shoot the Elite Grenadier with the EMBAR. The DR-1 actually finished him off. It was very satisfying to make this run.
Robotics Expert fares so much better than Mechanic, it’s not even funny. You get a Boltok which unlike the Talon, isn’t a piece of dog ■■■■ so that helped a ton. The DR-1 as an ult was a lot more useful since he is very tough and makes a good distraction. He can also kill stuff on his own too which is nice. If you want to solo this hive, you really want the sniper spawns. The non sniper spawns suck.
With Mechanic, the furthest I got was the final room with the snipers and Scions. Couldn’t kill everything with him. Robotics Expert with his bleed and better ultimate made this possible. Again, maybe @TurnerBurner922 will pull off solo on The Hive with Mechanic one day.
Oh and I was running:
