title

[Cop Unit 12]

Swat, Engineer (energy shield is very good), or Pyro (with the flaming axe too lazy to open the game atm)

[Dalle79]

I did it on Hunter, with explosive arrow. Max Weapon cool down first, then go for Ability cool down to put out the monkey decoy as often as possible.

[Aztek]

Pyro was easy and relatively fun with Infernax and maxed out weapon cooldown reduction (weapon attack speed does nothing with this weapon, it works kinda like one-bullet-gun with no affection of firerate, but depends on reload speed).
Didn't even touched HP or armor.
I assume Eng will be not that hard, Energy Shield good with protection (though it feels like it's been nerfed in terns of damage) and Turrets can destroy train that follows you. As for weapon, Tesla is good enough, Laser and Blaster not the best when it comes to clearing the way.
Ghost should be fine too. Dodge, crits and fast Thousand Cuts, plus Hologhost is nice.

[Ruud]

I did it with Swat. Focusing weapon damage by going Sniper + Richochet (I max out richochet before going sniper, to prevent a balance drop in damage output upgrading from Uzi). Usually I get 1 level chopper early on to help controlling horde. Further on I focus my leveling in this order Heli > Turret > Grenades. This in combination with picking items towards Crit chance, Crit damage , Weapon damage, Attack speed, Weapon reload reduction. Movement speed is also important. The one item I get for some durability is the 300 health + 5% armor item (can pick it twice)

My tactic to outlast it is to try kite enemies and let the sniper pounce through the horde with the penetration feature. Key is to position yourself so the shots hit the group. I do this by suing several tactics like walking the outercircle and shooting inwards, making a boss unit follow me close and use it as a target to line up the rest of the horde, or switching to manual aiming.

[Decoy]

Swat. With the constant upgrades after you finished maxing the swat skills, you'll quickly become very strong. Focus on the weapon upgrades (assault rifle). At the end of the run I had 100% crit chance, 350% crit damage, 210% fire rate, 224% movement speed, 75% reload speed, 75% armor, 2100 hp, 35% doge chance, etc... I let the horde kill me after 30 mins, it took 5 bosses about 15 seconds to finish me. The run was way easier than I thought .

[Ren Stoker]

Any character really. You just need to prep before you go in. I completed a 30 min solo on Green Hell using Medic yesterday. It was a lot of fun turning the weakest class into a monster
