I take back what I said guys. Tier 3 is very much different than Tier 2. I was not expecting the oilers to dash in front of me & around me like that. I felt like I was a wilder beast and they were a pride of lions. There is a lot of oil, LOTS & LOTS. One oiler is already a big threat. I would like to form a full party & do a full party run to see if Compound 42 is an impossible mission. Right now, what I feel should be nerfed is probably the .... hm I'm not sure exactly. I just know that it was very hard to kill the turrets because of the massive oil around the polyps which only gave me the option of using range to take them down but of course, that would be impossible to do when I'm being attacked & being brought down to my knees by those lions a.k.a. oilers.
So let's form a party guys, I go by Darth-Viruu in the testing server so send me a friend request and let's set a time when we should do this mission together. So who wants to try teamwork tactics because this is basically the only option we have in doing this mission. It's still not impossible to do but it demands a good team to accomplish this mission with out energy revs & just to accomplish it period(i mean this if compound 42 was published as it is right now).
But like Rawrcare has said, carrying poison defense is the best & a definite recommend for this mission. The oil is the biggest threat which makes the monsters very hard to fight.
P.s. This mission demands different player attributes(if you're not carrying poison resist that is).
I as Darth-Viruu am using Chaos Cloak. What I loose in defense I make up with damage & swiftness. Plus I have knock-back so I know how to kill the oilers without being exposed to it's sludge after killing it.
The mission is not made for solo. Maybe you need a party to complete it. By the way, I have solo it. Well I just use 5 revive. At least I can solo it. Nothing impossible in this world.
