Blood Music

From publisher blurb:

This is an interesting little investigation for a group that have never played Cold City before but have heard about it and want to give it a try; I've run it several times and even used it as the basis for a campaign. The version here is playable from start to finish in 4 hours and has space for four players.

An investigation of an unexplained death opens up some unexpected cans of worms, exposing betrayal within the RPA, commercial interests in twisted technology and an invisible war between powerful alien entities, any of which could lead to the end of the world by sunset.
No pressure then.
