The Silhouette system was produced by publisher Dream Pod 9 and suits their form of heavy space opera RPGs. The system is based upon rolling multiple d6s and the results exaggerate the effect either way. A big success roll results in highly positive effects, a bad roll means you suffer more damage for example.
There were three editions of the system, with Dream Pod 9 bringing out a Silhouette Core rules book to enable all their games to be run from one system:
- CORE Command
- Gear Krieg
- Heavy Gear
- Jovian Chronicles
- Tribe 8
and others. There are also methods for converting Silhouette to d20 to enable players to use d20 sourcebooks.
The Silhouette system is generally well received for the genre and has mostly positive reviews.
