- — In-game description.
The weapon only appears in the mission "Utopia". After getting out of the sewer, when Ilona and Mitchell are informed by the anonymous helper that Atlas is rounding up civilians, two enemy snipers wielding the Atlas 20mm can be seen on a bridge. Their position is unreachable, but it is possible, though very hard, to obtain the weapon from one of them.
The most effective way to do so is to shoot a sniper in the head while he is in the middle of the bridge (using Overdrive is recommended for this), in which case he might drop the weapon from the top. It will reach the ground where Mitchell is, and the player can pick it up. Before shooting the sniper, it might be handy to kill all the soldiers on the ground, then go slightly forward to the buildings so that "checkpoint reached" appears on the screen. As such, the player can deal with the snipers without worrying of nearby enemies, and repeat the process as many times as desired if they couldn't get the weapon in the first attempts.
The Atlas 20mm is unlocked at level 38. It is a very high damage per bullet sniper rifle. The Atlas 20mm scores one hit kills to all parts to the body bar the shins. In hardcore game modes, the Atlas 20mm is always a one shot kill, and its obscene power can also result in one shot kills through objects, as the Atlas 20mm also has very high penetration power. The Atlas 20mm is by far the most reliable sniper rifle in terms of netting one hit kills.
The Atlas 20mm has a low rate of fire for a sniper rifle. It fires in a semi-automatic configuration at 300 RPM, or five shots per second. While the Atlas 20mm doesn't heavily rely on follow-up shots, the Atlas 20mm can endanger the user somewhat if the user misses or needs another shot to kill an enemy.
The Atlas 20mm's accuracy is horrible. Its scope has a small field of view and will sometimes fail to fully render, the Atlas 20mm has the highest amount of idle sway in the game, the Atlas 20mm sways faster than all sniper rifles when prone, and the Atlas 20mm has heavy recoil per shot. The inaccuracy of the Atlas 20mm is the weapon's biggest problem and poses a challenge to players.
The Atlas 20mm has bad handling characteristics. The Atlas 20mm restricts the user to 90% of the base speed, aims down the sight in 400 milliseconds, has terrible hip-fire accuracy (although hip-fire is only accessed in the middle of the aim down sight procedure), and the Atlas 20mm reloads slowly, taking at least 2 seconds to reload cancel the Atlas 20mm, 2.3 seconds if empty, and a Speed Reload takes 1.45 seconds to reload cancel. The Atlas 20mm has the overall slowest reloads in the sniper rifle category.
The Atlas 20mm has a four round magazine, and sixteen in reserve for a total starting ammo loadout of twenty rounds. This is a small loadout for a sniper rifle, but considering that the Atlas 20mm uses ammo efficiently, this is acceptable.
The Atlas 20mm has a limited set of attachments, as all optical modifying attachments bar the Ballistics CPU are restricted, while the Suppressor and Tracker are also absent. The Ballistics CPU is a very powerful attachment for the weapon, as it helps regulate the Atlas 20mm's ludicrous amount of idle sway. The effect is also intensified when using it on the Hypersonic, Interrupt, or 13 Twist variants, which also decrease idle sway speed.
The Stock is useful when the player wants to extensively aim with the Atlas 20mm in confined spaces. However, it is fairly useless otherwise.
The Parabolic Microphone reveals suppressed weapons fire when the mini map is visible and the Atlas 20mm is currently in use. The effect is of questionable value.
Extended Mags increases the Atlas 20mm's magazine capacity to six rounds, and boosts the starting ammo loadout to thirty rounds. If the player wastes ammo easily, this attachment is very useful.
The Atlas 20mm has some good variants to use. The 13 Twist and Interrupt both lessen the effect of idle sway by reducing sway speed by seventeen percent. However, this comes at the cost of a lower fire rate and 2% less movement speed for the respective variants.
The Virtuosity and Royalty both reduce the sprintout time by thirty percent, which is extremely useful when aggressively using the Atlas 20mm.

The Atlas 20mm is unlocked upon reaching round 24; it costs 3 upgrade points. Unlike its multiplayer counterpart, it can equip a Variable Zoom Scope.
- If the player turns to the right side at high sensivity and then aims down sight, it is possible to see through the weapon.
- On the side of the weapon, there are thirteen tally marks plus two jet drawings. This can be seen when spinning to the right at a high sensitivity.
- There is also text reading: "Before Handling Read Manual From: BALDR RIFLEWORKS"
