Core Mechanic
2d6 + attribute mod + skill for skill checks; d20 + modifiers vs. AC for combat. Edge and chrome (cyberware) add abilities and complications.

Considerations
OSR combat can feel basic, cyberpunk genre may overlap with Shadowrun expectations, less support for narrative/story-arc campaigns
