Free beta. No account, no install, no upload: your recordings stay on your computer.

Overmerge replaying a DCS World merge: Su-27s and F/A-18s with their trails over the map, the range and aspect between two of them, and the debrief panel listing each shot and what happened.

What it does

  • Replay in 3D

    Aircraft, missiles and ground units over a map or a tactical grid. Orbit, follow, top-down and cockpit cameras; play, pause, step and jump to any moment.

  • Debrief every engagement

    Shots, hits, misses and kills, the chain of events behind each kill, and the timeline of who was where when it happened.

  • Reports and squadron stats

    A report of the mission to print or share, CSV exports, and statistics that add up across your squadron's sorties.

  • Bookmarks and share links

    Mark the moments that matter, add notes, and send a link that opens an online recording at the right second.

  • Big files, quickly

    Recordings are read in the background with progress you can cancel, including .zip.acmi files.

  • Private by design

    Everything runs on your machine. No analytics, no tracking, no cookies. Privacy

How to start

  1. Record a flight as an ACMI file (.acmi or .zip.acmi), the format DCS World and Falcon BMS recorders write.
  2. Open Overmerge and drop the file on the window, or choose Open. No file to hand? Open the sample flight.
  3. Play it back and open the Debrief tab.
