Intrude is a first-person shooter. Your mission is to get into a long time abandoned base, suddenly taken over by some kind of private military, find your way up and destroy the source of a signal comming from the base. Collect as much data as you can to find out what they are up to.
I tried to transfer the fun and a large number of enemies from the game serious Sam the first encounter.there is no music on the map, so you can include the original theme from the Serious Sam game
