Picture shown is what the Tactical Observer looks like, now find it. DO IT NOW.

Once you've found a floor with one of those things, clear out the stage EXCEPT the rotating dildo. He's gonna be helping us ;)

Tactical observer upgrades every 25 seconds in combat and the drones that this guy spawn does not hurt you if you dont move. Having the drone follow you still counts as combat.

Now find a comfortable spot to wait for 5 minutes.

Once you've waited for approximately 5 mintues, a warning should appear just like the picture above.

You HAVE to kill the executioner.

Once you have killed the executioner, then you can wait as long as you like.

Now that the executioner is DEAD. You can wait on the floor as long as you like, Im not joking you can leave this overnight and get 1000 upgrades. This took atleast 6 hours to get to stats like that, but you can go up infinitely.

While waiting for the gun to upgrade, you can actually play other steam games BUT you cannot play multiplayer sadly. If you don't want to then its fine you can just binge watch youtube or leave your computer overnight.

When you get back from playing other steam games, synthetik should have a massive FPS drop and that's fine. If you're not satisfied with the results you can leave the game like that. But if you feel like its done just teleport to the next floor and the fps lag should stop.

ENJOY YOUR RIDICULOUSLY OP BLUE WEAPON!!!
