Alright so here is my feedback for the second Danger Mission (Tier 3 Verson):

Okay, this mission is too painful. I played this mission in both solo and in a party, and this mission was too hard to navigate through smoothly, even with infinite energy. I do like how the levels looks for this area, but the obstacles you have to put up with to progress is beyond ridiculous. There also is an issue with the fact that most of the level is tight spaces, (And constantly being poisoned/burned with little to no way it to avoid it in most cases.) This made the Oilers even more difficult to eliminate, and certain traps at times not avoidable. (Example would be the beginning of the second level.) There really does need to be some nerfing in certain areas within this mission, especially with the new lichen's blobs of oil it leaves on the ground.

-Monsters:

1. Biohazardous (Nuclear) Oilers:
This enemy is too difficult to handle in battle. The fact that it's oil INSTANTLY poisons you on contact and it functions the exact same way as an oiler and toxigel (except the dash move it uses, which is quite hazardous on the battlefield.) The fact that their oil blobs spawns very frequently makes it almost impossible to restore any health in battle whatsoever. These enemies make this mission a "No Healing Survival Challenge" as of now since these enemies make all Health Capsules almost insufficient. Adding any Gremlin Scorchers/Red Rovers/Fire Traps with these enemies is pretty much a death sentence for the area. Work needs to be done on this monster to make it easier,.

2. Biohazardous (Nuclear) Polyps:
These are slightly less painful than the monster above. My only concern is that the fact that they LOB (a.k.a. spawn) ONE OF THE OILERS AT YOU AT TIMES!

3. Biohazardous (Nuclear) Toxilargo:
This pretty much was a cruel joke of a giant verson of the oilers. This monster died in a few seconds by a randomly placed Retribution. Kind of glad this abomination didn't cause much more chaos than the regular verson.

4. Gremlin Firemaster (Herex? Maybe not:)
This also was easy to kill, it was just a giant Gremlin Scorcher with two flamethrowers.

-Recommended Gear from what I've seen:

1.Swords: Acheron (Gran Faust too maybe,) and Glacius

2.Guns: All Pulsar-line weapons, Sentenza, or Hail/Umbra Driver

3.Bombs: Dark Retibution or (I really do not like recommending this bomb at all, but this mission does need a tone down in difficulty in any way.)

...Shivermist Buster
(Not sure about Electron/Graviton though, might be good to bring to hold some of the enemies in a place that won't be so dangerous for the team to do any fighting in.)

4. Armor: Either Full Dragon Scale OR Deadly Virtulisk + Any Volcanic Armor

5. Shield: Dragon Scale (Pretty much unbreakable in Oil Blobs, even ones on fire. Be aware though this either locks you in place or makes you move sluggish, making it more likely for you to get hit by an enemy's attack.)

That sums it up about what I feel about this mission, the contsant and almost inevitable burning and poisoning just made this mission difficult to the point it was not enjoyable. The dying was due to the fact that the enemies (mainly oiler,) can manage to get a lot of damage on you, and since you are constantly poisoned by the blobs, health capsules and spare hearts on the field are almost useless. This area pretty much is at a constant difficulty as that last room/last wave (hardest part) of Legion of Almire, but with the whole idea of having oilers spawn/go through fire in most areas of this mission, much like the Shadow Lair Variant of Ironclaw Munitions Factory.

Sidenote: I already have an image of all four new monsters, going to post them on the wiki and the info on Herex once the mission is released.
Edit: Added other areas to the game for referencing difficulty.
