Intruder

An Intruder has been located in the higher layers of the Complex

Cooperate with or fight against the individual called the Intruder

Or play unrelated levels with stupid gimmicks - Protocol Extended

Many things won't go according to plan...

Better-Vanilla type, Intermediate to High difficulty levels (B - E difficulty, maybe F later if I'm feeling evil...), many times stealth is optional, levels often have enough ammo for room for error

Wiki for new enemies included!

Unique level concepts with unique gimmicks all around that I haven't seen much of, if any, executed.

There is a story to follow in the rundown. More often related to the current level you play, but I have put in a lot of effort in terms of messages mid-play to present it. If you miss reading them, it's just going to be more difficult for you to understand what's happening :) but whatever, right? unless you are a lore fanatic

Ok, cool, what's new that you offer compared to what is in Vanilla?

• Custom gear with attention to detail - weapons, tools, and melee weapons with and without gimmicks or abilities described as best as one could
• Custom objective ideas
• Some semi-basic lore to follow
• Custom enemies (20 new enemies as of writing this description, 11.2025)
• Slight lack of vagueness as to what is happening around you or what will happen
• Load of Quality of Life mods that make the gameplay so much more smooth; however, there are no mods that fix useful exploits

Now, I'm not saying other rundowns don't have this, of course, this is just a very honest description of what we have goin' over here without sugarcoating anything

What is banned from use in the rundown? (aka don't use it or it won't be fun anymore)

Any mods that upgrade your movement, add additional gear to choose from in levels, or increase your stats - you are busted enough for each level, and if not - please complain about it in the feedback on the Discord. Banned specifically:

• Bow (breaks level balance)
• DoubleJump/ApexPrisoner/NoStamina (brother, if you want movement then you should probably just equip the Star Fist or the Knife...)

Other than that, feel free to download the QoL standalone of preconfigured plugins as a modpack for a better experience in other rundowns.
