Note that the enemies do not actually use these weapons, they just drop from timed loot. Think of the enemies as couriers, and your soldiers as those who rigged the game from the start. None of them can be reverse engineered, so feel free to sell them to the Black Market if you don't want to use them. Enhanced and Master-Crafted versions are available as well as the standard versions.

All Advent primary firearms only have 2 attachment slots, as opposed to the other primary firearms in ABBA which have 3 (just like LWOTC primary firearms do).

• Advent SMG: The Advent SMG is a light weapon, allowing the user to make use of a Strafing Shot ability that grants a half-movement action following a shot. Critical hit chance and critical hit damage are both high. This weapon is very accurate up close, but accuracy falls off at range as fast as a shotgun's does. Unlike the ABB version, this one has access to Standard Shot as well as Strafing Shot. Unlike most typical SMGs, this one does not offer a mobility or stealth bonus, but its infiltration bonus is better than other SMGs.
  
  
• Advent Enforcer Rifle: The Advent Enforcer Rifle is a cutting edge pacification weapon, the next step following Advent's successful Project Miranda experiments and is an alternative to the Skirmishers' bullpups. It can fire rounds that induce fatigue in any target, including mechanical ones. The shots don't need to connect to impart this effect. This rifle's accuracy does not change much regardless of the distance from the target.
  
  
• Advent Inducer Carbine: A variant of the Advent Priest's rifle and serving as an alternative to our soldiers' Assault Rifles, the Advent Inducer Carbine's primary function is that of a catalyst rather than a weapon. It only offers SMG-level firepower, but it also features an internal biological Psionic component, similar to a miniaturized Gatekeeper; it can manipulate the wielder's mind, body, and gear alike, resetting all ability cooldowns. Killing seems to amuse the biological portion of the weapon; it will lend you more of its power the more kills you get, even if they're not with this weapon. Try not to think about the ethical complications of this one. The Advent Inducer Carbine is about as accurate as a standard Assault Rifle.
  
  
• Advent Shotgun: The Advent Shotgun is easy to handle and yet cumbersome to reload. The user will be able to hunker down automatically if they don't attack. Although its ability to hit critically is lower than a typical shotgun, the Advent Shotgun can fire breaching rounds that easily destroy any cover they hit. This shotgun has two options for reloading: Single Reload, which loads one round for one action and does not end the turn, and Full Reload, which loads an entire magazine for two actions.
  
  
• Advent Scout Rifle: The Advent Scout Rifle is designed for use by reconnaissance units. It doesn't hit as hard as a sniper rifle, but it can be fired even after moving. It can also be fired without moving and then followed up with a half-move, but only once per turn. Compared to a regular sniper rifle, this rifle is a little more accurate up close, but a little less accurate at range. Unlike the ABB version, this one has access to Standard Shot as well as Snap Shot.
  
  
• Advent Breaker Rifle: The Advent Breaker Rifle has amazing burst damage and is a powerful alternative to the Reapers' Vektor Rifle series, which is as accurate from range, but much less so up close. It is designed to fire its entire magazine at once, which means it must be reloaded after every burst. This Advent take on an auto-sniper rifle fires smaller caliber shots and has an integrated compensator, eliminating the need to steady the weapon prior to firing. This weapon cannot equip Auto Loaders or Extended Magazines.
  
  
• Advent Smartgun: A compact cannon with electronics that allow for automatic tracking of targets. Its effective range is similar to a standard cannon or LMG while damage is slightly lower. Whenever the soldier takes a standard shot, the weapon will enter Overwatch mode. Advent Smartguns also fire automatically against hostiles in close range. Comes with a massive magazine, but reloading costs two actions. Requires two actions to fire, but also enters Overwatch after firing. Regular Overwatch still costs just one action. While in ABB, Reactive Fire had a 4-tile radius, here the radius is 5 tiles in order to better suit the Smartgun's ideal range.
  
  
• Advent Persuader Pistol: Named after its popularity among Advent officers for torturing information out of captured enemy non-combatants, the Advent Persuader pistol is an alternative to the Templars' autopistols that makes up for its low stopping power with excellent handling. It can be fired in close range without spending an action once a turn and cannot be dodged. Accurate up close, but falls off at range just as most pistols do.
  
  
• Advent Acid Launcher: A madman's creation; the Advent Acid Launcher fires the same sorts of acid blobs that the Andromedon does. Unlike with an Andromedon's acid weapon system, this launcher cannot produce acid indefinitely and is limited to 2 charges per mission (improved versions carry more). Although it resembles a standard grenade launcher on the outside, its internals were designed for its own acid blob rounds only and cannot fire grenades, thus provides no range or radius bonus to them. The launcher must cool down between shots. The Advent Acid Launcher deals pure acid damage, and as such will not destroy loot, is not resisted by abilities like Blast Padding, and won't attract Lost very quickly, but won't deal any damage at all to enemies immune to acid like Andromedons or Bio Division units.
