Void Mission Zero

Overview

Void Mission Zero is a sci-fi roguelike game written in Common Lisp. You play a lone agent infiltrating an automated droid factory in order to destroy the enemy robots within. To win the game, you must fight your way through the corridors and chambers of the factory, cutting through the countless robots infesting the site, and make your way to the reactor area. There you must destroy the cooling towers, which will cause the reactor to explode and destroy the factory.

Basic weaponry

You begin the game armed with a rusty wrench; at some point you obtain a ranged particle gun. The particle gun needs batteries; these can be found randomly in supply crates, or taken from the smashed remains of robots. (Sometimes supply crates have evil robots in them, too, who'll jump out and surprise you.)

Grenades

There are also two types of grenades. First we have electromagnetic pulse (EMP) grenades, which damage and temporarily freeze robots (and you, if you're not careful!). On the other hand, there are conventional explosive grenades, which do more damage and have no freezing effect.

Perceptors

Enemies include various Perceptors (floating spheroid eye-bots with shock probes). Red perceptors tend to seek the player even when far away, but purple perceptors wander around randomly until the player comes near. These are very dangerous to the player, and he must have a ranged weapon in order to deal with them effectively.

Rooks

Rooks are large, slow, tank-like turrets-on-wheels. Their roof-mounted particle cannons are accurate and extremely deadly, but have two disadvantages. First, they cannot target immediately adjacent squares, so the player can survive by getting close and attacking with a melee weapon. Second, the particle cannon is slow to recharge, allowing a shot only once every few turns.

Being in an open area with several rooks is a bad idea—they'll blow you away. Instead you must lure them one by one into corridors and fight in close range—or freeze the group with EMP grenades and blast away.

The Diskarmor

The Diskarmor Industries Model 1008 is a semi-autonomous rolling robo unit. It can be thrown in one of the eight compass directions; upon colliding with anything, it will do a good amount of damage, and release shots. So you could throw it down a corridor and have it take out a few robots when it hits the wall at the end. The Diskarmor will return to its operator after throwing.

Other

Two types of levels: Corridors (i.e. long, unidirectional strip-like levels with many distinct sections or rooms) and Chambers (sprawling mazes or arenas.)

Player attributes are a bit simplified when compared with a typical roguelike. Strength, Dexterity, Intelligence, Constitution, Hit Points, Psi Points, etc.
