How to run (digital)

Recommended stack

Voice: Discord or similar
Dice: Built-in #roll or Avrae; macros below
Sheets: Each player opens operator-sheet.html in a browser tab
GM: map-kreslia-port.html + scenario-01-first-contract.html + quick-ref.html + enemies.html

Session flow (~3 hours)

Hideout / pre-op (15 min) — hideout.html + hideout-sheet.html — point buy, pick loadout, buy ammo, downtime actions
Operation (90 min) — Run Scenario 01
Post-op (15 min) — Loot triage, injury resolve, insurance — back to hideout

Point buy (27 pts)

Scores 8–15 before mod bonuses. Cost: 8=0, 9=1, 10=2, 11=3, 12=4, 13=5, 14=7, 15=9. Mod max +3.

Roll20 / Discord macros

Hit: /roll d20+@{dex_mod}+@{prof}
Location: /roll 1d12

Exfil clock

Track 3 segments on screen or paper. +1 segment per: gunfire without suppressor, failed stealth, extra POI after objective complete, body not recovered when dragging. At 3: exfil contested — roll encounter table in scenario.
