Tunnel Goons

Tunnel Goons is system-first and setting-agnostic. It shines for classic dungeon crawls, weird wilderness hexcrawls, and quick urban capers.

Theme and Setting

Tone leans scrappy and lethal at low levels, rewarding creative problem-solving over build math. Characters have three broad stats (Brute, Skulk, Wits).

How Play Feels

When you attempt something risky, roll 2d6, add the highest applicable stat, and compare to a target number set by the GM and situation. Gear and advantage can add small bumps; harm and hindrance push the TN up.

What Makes It Distinct

Combat uses the same contest - no separate initiative mini-game - so scenes resolve quickly. Advancement is intentionally light: groups often tack on milestone perks, item unlocks, or scars to taste.

Where It May Not Fit

You want the system to stay almost invisible at the table You want a much breezier tone than this game is built to support.
