Deadlock: Planetary Conquest is a 2D turn-based 4X strategy. Players take the roles of aliens deadlocked on a planet surface. The game has seven different races with special abilities, for example the Maugs are great scientists, ChCh-T have the highest birth rate etc. They spend turns building, expanding, and ultimately warring. The planet's surface is divided into smaller areas. Each area is home to one of the cities that need to be constructed. To colonize a new area, the player must build a colonizer. Players can expand their cities by erecting residential buildings, farms, factories, mines and research centres. Inventions made in the latter provide new units, new materials and better buildings (for example a hydroponic farm is far better than a normal farm). The residents' satisfaction is important - dissatisfied citizens (taxes are too high) protest and don't work.

The battle begins after the player places their units in a foreign land. Battles are separately animated - after being initiated players have no control over them. The game also has a spying mechanic that spies can use to steal technologies. The player wins by fulfilling one of the victory conditions, for example remaining the last living race on the planet, or reaching a set number of city centres first.

Known bugs as of version 1.31 (from patch readme.txt):

Deadlock doesn't terminate completely on exit. Upon exiting a multi-player game of Deadlock, if you try launching a second game of Deadlock the message "Cannot run multiple instances of a DLL under Win32s" appears. Press CTRL+ALT+DEL to bring up the Win95 task list. Select and END any running Deadlock tasks. You can now play Deadlock again. [Win95 only; on TEN & Mplayer online services]

Cover misprint

Some CDs of Deadlock: Planetary Conquest have the designation "Retail Demo" printed on them by mistake.

Demo version

If the game was played without the CD, a demo of the game was available to play. However, the demo was so limited that it defeated its own purpose.


During the game's development, there was some discussion about making it a real-time strategy game, instead of a turn-based one.
