A semi-automatic anti-materiel rifle capable of inflicting massive damage to Titans for each hit, chambered in 14.5x114mm DU penetrator APFSDS, designated Keter. The high-explosive 20x102mm as well as other 20mm rounds with varying payloads is officially listed as "experimental" by the IMC, but it has been deployed in several missions.

In-game short description

The Sentinel Anti-Titan anti-materiel rifle, designated as R-2818 "Black Widow", or simply known as Sentinel-AT AMR is a recoil-operated, electromagnetically-actuated, bullpup semi-automatic anti-materiel sniper rifle developed by the Lastimosa Armory, first appeared in Titanfall 3. Despite its designation as an anti-Titan weapon, it is used by some armed forces as an anti-aircraft/anti-personnel sniper system. It is chambered for 14.5x114mm DU penetrator APFSDS, designated Keter though it can also be chambered for 20x102mm and the new 25x82mm payload rounds including the TPA-based high-explosive incendiary and the thermite-based incendiary rounds, designed to burn down both Pilots and Titans.

It has a unique charge mechanic, derived from Sentinel enhanced sniper rifle platform. When charged, bullets fired from Sentinel-AT AMR will completely break Titan shields in one hit and deals extra unshielded damage, making this already dangerous weapon even more dangerous.

It's a higher-caliber, semi-automatic variant of Sentinel ESR and Sentinel-AP Sniper to fire more powerful 14.5x114mm rounds at hypersonic speed. It retains the charging mechanics from both original Sentinel and the .50-cal variant.

The Plasma Charge hop-up changes the charge mechanism in order to utilize the release-to-fire mechanic of Plasma Charge hop-up on any semi-automatic weapons.

Overview[edit | edit source]

The IMC wanted to replace the Kraber-AP Sniper with the more powerful, semi-automatic one now known as Sentinel-AT AMR. The Sentinel-AT AMR wins the bid for the semi-automatic anti-materiel rifle that can effectively take down both Titans and dropships. The IMC also wants a long-range anti-Titan weapon that is neither bolt-action nor single-shot.

Description[edit | edit source]

It is a recoil-operated, dual-stage, bullpup semi-automatic anti-materiel rifle, designed for use against Titans. It has battery magazines to allow any energy sources to charge shots with more damaging effect. Additionally, the Sentinel-AT AMR uses electromagnetic propulsion to drive 14.5mm APFSDS round to the hypersonic speed and 20mm payload round to approximately 2,000 meters per second. When charged, Sentinel-AT AMR injects plasma into projectiles, making it more dangerous and it can burn anything flammable even if ammunition is not incendiary.

The 25x82mm ammunition, derived from 25x59mm ammunition for both Sentinel-AP Sniper and PB-504 anti-materiel rifle are designed for Sentinel-AT AMR as a high-velocity grenade launcher.

Pros and cons[edit | edit source]

  • One shot kill against Pilots regardless of body parts.
  • High projectile speed.
  • Bullets penetrate enemies, allowing you to hit multiple targets with one shot.
  • Charged shots will break the Titan's shield on hit.
    • Charged shots will have an additional energy damage.
    • Can inflict massive damage on longer trigger pulls using the Plasma Charge hop-up attachment.
  • As an anti-materiel rifle.
    • Can open doors by shooting the handle.
    • Can sever Titan's hands and ordnances.
    • Can temporary slows down or even immobilizes Titans.
    • Bullets will go through thick walls, making it possible to wallbang Pilots and kill inside Titans.
  • High recoil. The recoil is so strong that rapid fire is inaccurate.
  • Low magazine capacity.

Trivia[edit | edit source]

  • Sentinel-AT AMR is inspired by PTRS-41 anti-tank rifle and Barrett XM109 anti-materiel rifle.
  • The R-2818 designation references an SCP-2818, a semi-automatic anti-materiel rifle capable of launching users through anomalous means[1].
