Seed

Seed is a cancelled PC game by Human Soft. It was to be a first person shooter set in the distant future.

Plot
Humanity has been in a very long struggle with Aliens. The people of Earth rebel against their useless governments and riots flare up. The Aliens launch their secret weapon - the Seed - which will civilization from beneath.

Our hero is a mercenary who has had experience working for organised crime. He looks like yellow-brown humanoid wearing no clothes. Our quest is to destroy the Aliens and their seeds.

Gameplay
Our protagonist has a weapon permanently affixed to his right hand, held in place by tentacles. We can switch between weapon modes: nail gun, missile launcher, and buzzsaw for melee attacks.

This game was notable in its Quake-like level design, with lots of verticality. Some of these levels were probably re-purposed as multiplayer deathmatch levels.

Cancellation
Seed was cancelled around late 1999 due to being unable to find a publisher.

Prototypes
Both demos.
