WorldKiller: The Game of Planetary Assault
From Wikipedia, the free encyclopedia

WorldKiller: The Game of Planetary Assault is a science fiction board wargame published by Simulations Publications Inc. (SPI) in 1980 that simulates humans in the far future defending a planet against an alien attack.
Gameplay
WorldKiller is a two-player board wargame in which one player controls aliens who seek to destroy the planet Greendream, and the other player controls the humans defending Greendream.[1]
The map is divided into an eight by twelve grid. Each square represents a three-dimensional stack of seven cubes, and placing a counter on various markings in the square indicate on which of the seven levels a counter is located.[1]
The alien player either passes or performs a single act with one ship:
- Jump to another part of the board
- Attack
- Stretch a longer Jump produced by delaying the Jump for a number of turns. Only alien ships can Stretch.
- Pop: Move and attack in a single turn. This is the only time a ship can do two actions at once, but the ship takes two points of damage as a result.
- Repair
Once the alien player concludes the ship's action, that ship counter is inverted and cannot be used again that turn. Play passes to the Human player, who also either passes or performs a single action with one ship. Play passes back and forth between the two players until both players pass, bringing the current Game Turn to an end. All ships that were inverted are turned face-up, and the next Game Turn begins.
There is no set number of turns — the game continues until the aliens either destroy the planet, or become so weakened that they cannot destroy the planet.
The game includes several optional rules, including reinforcements, missile cruisers, a new type of human ship, and variable unit strengths.
Victory conditions
The aliens win by destroying the planet. The humans win by preventing this.
