Best For

Groups who want a crunchy BRP-based sci-fi game where superpowered agents travel to other dimensions on tactical missions, build up a shared base between operations, and face detailed combat with location-based wounds.

Core Mechanic

Roll d100 equal to or under skill value for a standard success. Degrees of success scale with the margin: standard (full value), difficult (half value), very difficult (quarter value), legendary (01 only). Misfortune triggers on rolls of 96+ (99+ for skilled characters). Combat uses initiative based on Dexterity, with major actions, minor actions, and reactions (number limited by Dexterity / 30). Defenders choose to dodge, parry, counterattack, or maneuver as reactions. Superpowers cost energy points and risk destabilizing the dimension when used in front of witnesses.

High

The d100 core rolls under a skill, with degrees of success scaling by margin. Most of the weight is in character building, deep on its own. A superpowers system of Aurora Effects adds another deep layer, joined by specializations and injury rules. The two together reward study before play.
