Warhammer 40.000: Agents of Death is a cancelled FPS that was in development by Mirage Media (mostly known for Imperium Galactica and Mortyr) in the late ‘90s, planned to be published on PC. The game was about the confrontation of 3 heroes against the ruler of a certain planet who sold himself to the forces of chaos. Before the beginning of each level, players could choose between one of the 3 protagonists, while the other two would have been controlled by the AI.
Levels had different objectives following the game story and one character could have been more useful than the others depending on the mission. For example if you had to kill one specific target without alerting the other enemies, a sniper would be the best choice. Instead in a mission with dozens of enemies to kill, someone with a huge fire-power could be the best choice.
Mirage Media was working on Agents of Death along with Mortyr 2 and both games used their homespun three-dimensional engine, which (according to the developers) made it possible to create an incredibly realistic and detailed world. Unfortunately they were not able to complete the project and in 2000 Agents of Death was scrapped.
It seems a playable alpha version of the game was leaked online many years ago: if you still have a copy of this, please let us know in the comments below!
