Havok Brigade is a game of elite humanoids invading a human city to perform dangerous stealthy missions behind enemy walls. It is massively influenced by Warhammer Fantasy in terms of its gothic, slightly silly, techno-fantasy.
The game uses a shared pool of dice to both represent the alarm and suspicion of the humans but also a resource the orcs can dip into to help win challenges vital to their mission.
The game is very focused and slight, the bulk of the game is the various character sheets of the Orc commandos. It's hard to understand what kind of game it is going to be and I suspect it will play better with people who understand the background material.
