Advanced Guard Protocol

Advanced Guard Protocol (formerly known as Challenging Enemies Mod) adds several new guards, both low and high level.

This mod was originally released on the Invisible, Inc. forum August the 23rd as a hard mod but this is the first time it is available on the steam workshop.

It was originally designed to be a very difficult mod but has been rebalanced to more standard difficulty levels.

The mod adds:
At least two unique guards for each corporation
Alternate versions of default security guards
New tier 2 Elite guards
New OMNI guards
System admins(Pacifists that will try to recapture hacked devices)
New enforcers

In addition to that, the mod also adds lots of guard-related generation options, like extended patrol routes, allowing guards to open locked doors, and scaling the number of guards in midway and final missions depending on how long your campaign is. These additions are all optional and can be individually disabled.

And finally, if think the game is too easy we have the solution for you... or special "HARD MODE" where every guard is faster, smarter and deadlier, all for your masochistic needs.
(Using hard mode requires you to have the Sim Constructor installed, which can be found here:

Please upload your log file. It can be found in Documents/Klei/InvisibleInc/logs. It's more convenient if you click the Discord link above and post logs and questions there.

Hello! I really like the new challenges so far, but the mod makes my game freeze on 5th alarm level most of the time. The new enemy that is supposed to spawn via elevator does not appear, and the game is stuck in the "corps turn" phase infinitely (waiting for the guard/drone to appear, when there is none).
Can it be a conflict with other mod, or has anyone else encountered the same problem?

It does. If you use the campaign length option to make it less than 72 hours.

alright, might want to remove the part that says it makes shorter campaigns easier from the tooltip then.

Rebalanced Omni doesn't change the difficulty in a normal-length campaign. But with the extended campaign the final mission becomes harder.

does anyone know what "re-balanced omni" does? Just played a game without extended campaign and I am wondering how much easier it made it (expert plus, but custom cos extended campaign is off in case difficulty affects the setting)?

Refreshed mods and my save game loaded without any problems. Thank you!

After refreshing the mod, my savefile was slightly corrupted (rooms without agents were rendered undiscovered), but I assume this won't affect any further playthroughs.

I tried to run into the exact same situation again, using different methods to knock out the guards, and the bug did not occur again. Thanks for all your amazing work!

Thanks for the report, it should be fixed now.
