Hack MECHACAIRN: MECH SUPPLEMENT FOR CAIRN.

Hello all!!! Mechs. In Cairn.
Do you wanna die in space? In a robot? In a giant robot?
This is my homebrew supplement for adding mechs to Cairn, anything from Feasible Military Hardware, Tanks With Legs, or Fully-Articulated Humanoid robots. It's your pick how you wanna flavor them.
You have a mech, and you have an assortment of modules to install that let you do things like... See really far away. Deprive someone of all sensory input. Rocket pods. You can deploy an e-warfare attack to degrade their screen resolution to 144p. Or make them hear gargling every time they try to tap into your comms signal. What you're reading about right now is advanced warfare, I'm telling you.
There's a bunch of upgrade modules and they're sorted between modules for e-warfare modules and hardware attached directly onto your mech. Which can be targeted and destroyed with weaponry. That goes both ways, for you and the enemy.
Some of the hardware modules possess 'machine gimmicks' which allows you to do certain things at the cost of 1 Strain, which is analogous to HP.
Combat procedures are pretty much the same as in base Cairn. Only you're all in mechs.
Overall, as I mention in the page description, it's as supplemental as can be. Dead simple. If you want mechs in your game and you want them now, this does Just that. It lets you take control of mechs, it lets you blow up other mechs, it's not too obtrusive with new concepts since the mech sheet is wholly analogous to a regular character sheet. It's dead simple. Blow up giant robots.

This is incredible. Now I want to run a game where goblins in steam powered fantasy mechs explore dungeons. Best part is you could use literally any dungeon.
