Infinity Mission Overview & Guide

Main category on the board, consisting of a randomised string of stages taken from the base MPO (exception being the Easy difficulty, which always has the same arrangement of stages and exits). Each difficulty increases the total amount of stages by 5 (Easy - 5, Normal - 10 and so on…), additionally harder difficulties contain stages that cannot be found on easier ones. Difficulties also affect guard types and their damage, while it is generally safe to run around while being shot at Easy-Hard with a decent recruit, an alert on Extreme can get out of hand quickly.

The goal of the run is to find the Access Point as fast as possible, the position of which is choosen at random from 6 pre-defined ones (the same applies for the place of your spawn).

In order to spot the exit quickly, make use of the Surround Indicator found in the top-right corner of your screen, while it shows noise coming from all nearby enemies, it can also pinpoint the general direction from your current position towards the exit point, signalised by a single sound spike, see picture below:

An important factor affecting the AP search is the enemy status. Finding the exit on alert might be hard due to hightened enemy movements, which could obscure the AP sound spike.

Do take note the AP doesn't apppear as an “object” on the Surround Indicator, therefore it can't be easily determined at which floor level the exit is (this is especially problematic in the Hospital, where 3 different APs are located on different floors in close horizontal proximity of each other).

In addition to normal stages, special stages will appear during the run. These will require you to complete certain objectives in order to progress. Here's list of possible special missions:

  • Survive - Survive until time tuns out. Alert phase will be in effect the entire time.
  • Neutralize - Neutralize all enemies. If the enemy sees you, they will call for backup.
  • Escape - Reach the Advance Point. Alert phase will be in effect the entire time.
  • Rush - Reach the Advance Point before time runs out.
  • Avoid - Reach the Advance Point before time runs out. There are no enemy soldiers.
  • No Alerts - Reach the Advance Point without being seen by the enemy.
  • Spot & Kill - Neutralize all enemies. The enemy is equipped with stealth camo.

Escape Special Mission

Except for Normal where the order of special missions is always the same (S3 - Escape, S5 - Survive, S7 - Neutralize), these missions are, like stages, randomised and may kill a run. The worst ones are: Survive, which forces you to wait a range of minutes before spawning the AP and Neutralize that may be short or long, depending on the stage layout and amount of enemies. No Alerts, although exclusive to the Extreme difficulty, gives you a game over the moment you get spotted, requiring you to take a stealthier approach.


Memorising the placements of APs (especially easy on Normal) and monitoring the SI for single sound spikes is essential for achieving a fast time.
