Era Ten
A sci-fi space marine RPG¸ set in a future where humans and their four alien allies (known as the ""Tetra League"") have been infected by a ""pacification virus."" The PC's are rare members of the species who are immune to the virus¸ and are thus pressed into service as powered-armor marines who defend the league from outside attack. It uses the ""Free-style Roleplay"" system from Crimson Cutlass¸ and also comes with extensive guidelines for generating random missions and other scenarios. The Space Gamer magazine published two mini-RPGs based on this: Battle Born (in issue #1) and Guardians of Sol (in issue #5). The PC's gain abilities by downloading capabilities into their spacesuit. Use of these suit skills are the only types of rolls the player makes during game play. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H. Kim"
