Incubation: Time Is Running Out (also known as Incubation: Battle Isle Phase Four) is a turn-based tactics computer game from Blue Byte released in 1997. In the game, the player controls a squad of soldiers in a campaign against an alien threat.

The single-player campaign includes around 30 missions set in futuristic interiors full of aliens, as a squad of space marines battles to save the civilians and themselves. The game has some head-to-head and co-op multiplayer support via LAN and software such as Kali. There are three difficulty levels which influence parameters like monster respawn and damage rates.

Outside of missions, the main decision is which weapons and equipment to purchase to outfit the squad. A variety of weapons are available. Some low-level guns feature bayonets for mêlée combat, which form a substantial element of the game. Equipment like jetpacks, scanners, improved armor, stimulants and medical kits becomes available as the space marines accumulate experience points.
