Campaign mission
Mission 5: Losing Ground
Losing Ground is mission 5 of 16. The notes below are from guide write-ups cross-checked on 23 October 2026, not from a frame-by-frame capture.
From my notes. I lined this mission up against Game8's 16-mission order and the story beats that also appear in the ending and cast notes. For Losing Ground I kept only the sentence I could point at a source. I left keypad codes, safe combinations and enemy health out.
What the sources agree on
A retreat and defense mission. No extra story beat was stable enough to add beyond the position in the 16-mission order.
The reward listed for clearing Losing Ground is Ready Line loading screen. Rewards are operator unlocks, cards or XP tokens depending on the mission. They are not a difficulty setting.
What I am not publishing
Collectible counts, checkpoint maps and trophy text were not re-read from the console lists. A guide that invents a route is worse than a short one. When a patch moves a safe, a printed code becomes a lie.
The full order sits on the mission index. Length ranges are on how long the campaign is. Spoilers for the last two missions are also on the ending page.
