Tabletop Tower Defense is a set of rules for running physical tower defense games. This can be a minigame in an ongoing campaign, or a one-shot standalone game.
The rules here are complete, yet flexible enough to be implemented in any system or setting. The game is played in phases with gameplay happening in rounds. The base is ideally represented by a physical tower of blocks, otherwise base damage can be tracked on paper.
You can use these rules as published, or use them as a system reference document (SRD) to create something new. The rules are purposefully stripped of any narrative elements so you can play this in any setting or context.
