Instructions: Add additional tips
  • The Mortar Sentry is straightforward and effective, dealing solid damage at good range regardless of intervening objects. Beware of close-combat enemies however, especially agile ones such as the Hunter or the Assault Trooper, as the Mortar Sentry has no programming to avoid friendly fire and the impacts can easily be lethal to allies or even yourself. This is exacerbated by the inaccuracy of the 3 round bursts, which can ragdoll Helldivers from a significant range
  • The indirect fire of the Mortar Sentry makes it easier to protect by placing it in ditches or behind ledges, rocks or structures.
  • It's not recommended to use this Sentry on Retrieve Essential Personnel and Emergency Evacuation missions, as the Sentry is able to easily accidentally kill civilians.
