The SOS Stratagem

The SOS Stratagem is a lifeline for players in Helldivers 2, allowing you to call for backup when the going gets tough. This feature is particularly useful if you find yourself outnumbered or outgunned during high-stakes missions. To access this vital tool, you must ensure your squad is not at full capacity, as the SOS Stratagem is designed to fill the ranks with additional players.

Deploying the SOS Stratagem

Activating the SOS Stratagem in Helldivers 2 is a straightforward process:

  1. Enter the SOS Stratagem code: Up, Down, Right, and Up.
  2. Deploy the beacon by throwing it to a location of your choice.
  3. Once activated, the beacon sends out an SOS signal that continues until your squad is full or the mission concludes.

It’s important to note that the SOS Stratagem is available to all players from the start of the game.

Effects of the SOS Stratagem

When you use SOS in Helldivers 2, you’re not just calling for help; you’re inviting other players to join your mission in real-time. Your mission will pulse on the planet map, signaling to other players that you need assistance. However, for the distress call to be visible, other players must be viewing the same planet and have selected the same difficulty level as you.

Lobby Settings and SOS

The SOS Stratagem also interacts with your lobby settings:

  • If your game is set to invite-only, activating SOS will automatically switch it to public, allowing any player to join.
  • After using SOS, you’ll need to manually adjust your settings if you wish to return to solo play or restrict your lobby to invite-only.

Strategic Use of SOS

To maximize the effectiveness of SOS in Helldivers 2, consider the following tips:

  • Deploy the SOS Stratagem in advance of difficult encounters or when facing challenging objectives.
  • Avoid using SOS during active firefights, as it may not provide immediate relief due to the time it takes for other players to join.

By deploying SOS strategically, you can ensure that help arrives when you need it most, giving you a fighting chance to complete even the most daunting missions.


The SOS feature in Helldivers 2 is a testament to the game’s emphasis on teamwork and cooperative gameplay. By utilizing the SOS Stratagem, you open the door to reinforcements that can turn the tide of battle in your favor. Remember, Helldivers are never truly alone on the battlefield.

When the situation looks dire, don’t hesitate to send out an SOS and rally the troops for a united stand against the alien threats. With this guide in hand, you’re now equipped to make the most of the SOS feature and secure victory for the Helldivers.
