TREngine (Tactical Resolution Engine) Quickstart (PDF Only)

TREngine (Tactical Resolution Engine) is a TTRPG system based on some classic cornerstones of role-playing games.
Its purpose is to reduce the longest passages and the most time-consuming mechanics, leaving more space for the narration while emphasizing the tactical cooperation between characters.

This peculiarity makes it perfect for simulating scenarios in which large numbers of player and non-player characters are involved.
If solving challenges in role-playing games often involves interrupting the narrative to use game tools, TREngine aims to reduce this time to a minimum by creating quick simulations without sacrificing the relevance of the game mechanics or the complexity and diversity of the possible choices.

The TREngine (Tactical Resolution Engine) is compatible with the following Tin Hat Games' titles (list constantly updated):
