The best part of Space Marine 2 is three players standing back to back while a Tyranid swarm floods the screen. If you want to show that moment to the squadmates who fought with you, or to a friend who has not bought the game yet, this guide covers one method: record Warhammer 40,000: Space Marine 2 with DOR, trim only the decisive stretch, and send it as a dor.gg link. Campaign, co-op operations, wave-based Siege, and PvP tend to mix in a single session, and even one operation runs a while, so you first need a way to pin down where the scene you want sits in the recording.
The short answer
Launch Space Marine 2 on a Windows PC with DOR installed, and the lobby, operation select, combat, and results screens all land in one mp4. After you quit, open that video in the library, use the operation loading screen or wave alerts to find the fight you want, trim 30 seconds to a minute or so, and paste the dor.gg link into your squad chat. Tips for landing the start and end points precisely are in how to trim game clips.
How to send a Space Marine 2 fight
- 1Install DOR and launch Space Marine 2Install the free DOR app on your Windows PC and launch Space Marine 2 as usual. It became a supported game in the October 2026 app update, so DOR detects it automatically, and the recording does not break when an operation ends; it keeps going until you quit the game.
- 2Jot down the real time while you playOperations are long and one session can chain several operations and Siege waves, so when something memorable happens, note the real time on your phone. Recording starts when you launch the game, so subtracting the launch time from your note gives you the spot in the recording.
- 3Use loading and results screens to find each operationWith no notes, skim the recording for the operation loading screen and the results screen. Everything between them is one operation, and in Siege the wave start alert splits the scenes. The final objective is usually right before the results screen.
- 4Keep swarms long and parries shortA swarm scene needs to run from the moment the horde enters the frame until it is cleared, or the scale does not come across. A single parry, on the other hand, only needs 10 to 20 seconds from just before the hit to the end of the counter and execution; anything longer buries the point.
- 5Trim in the library and pick a ratioOpen the recording in the library and set the start and end points with the trim tool. 16:9 suits a horde filling the screen, while a short scene focused on one character, like a parry, also reads well exported at 9:16 for a friend watching on a phone.
- 6Send different cuts to squadmates and curious friendsSquadmates who fought with you will enjoy the minute or so of holding the final objective, while a friend still deciding on the game reacts better to a single swarm fight. Either way, pasting the dor.gg link in chat means nobody has to move a large original file.
Scenes to find and how long to trim them, by Space Marine 2 mode
| Mode or situation | Marker in the recording | Trim length |
|---|---|---|
| Big campaign battle | The swarm rushing in right after a cutscene hands control back | 40 sec to 1 min |
| Final objective in a co-op operation | The squad holding the objective just before the results screen | 1 min to 1 min 30 sec |
| Surviving a Siege wave | From the wave start alert until the last enemy drops | One wave |
| Parry and counter | The counterattack and execution right after you deflect a big hit | 10 to 20 sec |
| Calling reinforcements | The moment reinforcements bought with Siege points arrive | 20 to 30 sec |
| Last PvP capture | The final fight as the capture meter fills | 30 sec to 1 min |
Check before you send
- At least 20GB of free disk space remains (below that, recording stops automatically)
- Your time note and the spot in the recording point to the same operation
- The swarm scene includes the horde rushing in at the start
- The parry scene ends after the counter and execution finish
- You are fine with squadmates' names or chat being visible
- Squad talk picked up by your mic is okay to share
What DOR does in Space Marine 2
DOR is a free Windows desktop app, and when you launch Space Marine 2 it detects the game and records it with full-session recording. Everything from launch to quit is one mp4, and this game has no automatic clips that split operations or pull out kills, so you trim scenes from the recording yourself. DOR captures what your own PC shows, so squadmates' views are not included; game sound and your mic are recorded together, and NVIDIA graphics cards use NVENC hardware encoding by default. As the app settings note, recording stops automatically once free space drops below 20GB, and on days you do not want to record, you can turn off just this game in the full-session recording group in settings, with a confirmation prompt when you do. To combine several waves or operations, follow the steps in how to merge game clips and join them in the browser-based DOR Studio, adding text and background music.
