Our take on Intrude

The bounce point arrives for players who need layered progression systems: Intrude centers on moving through 15 levels, fighting through the base, and collecting hidden data. Those expecting character builds, extensive customization, or a multiplayer structure may find its focused FPS framework too narrow.

What is Intrude?

Intrude is a first-person shooter set in an underground base that had been abandoned for a long time before a private military group took control.

A strange signal is coming from the base, and the objective is to reach its source and destroy it. The game draws inspiration from older FPS titles such as Wolfenstein 3D and Doom. Progress takes place across 15 levels, with three game modes available. Hidden data is scattered throughout the base, giving players an optional collection objective and information about the occupying group and its activities.
