M4A1-S Under Tech is a specialized assault rifle variant of the M4A1 Silencer.
Overview[]
Like the AK47-Buster, this gun received an overwhelming change in design, with the carrying handle removed, a new barrel that can be open or closed when reloading to cool the heat, and an Under Tech Loading Gate mounted to the side that allows the magazine to slide in angled rather than vertically. Because of the new barrel's mechanics, player characters now hold the magazine instead of the handguard. M4A1-S Under Tech performs more or less similar to other M4A1-S variants with good firepower and accuracy, decent recoil, but it receives a unique faster drawing/reloading animations than most other M4A1-S (only behind the VVIP variants). Plus, this weapon has full wallbang damage.
In Zombie Mode, this gun becomes an Anti-Zombie Weapon and receives ammo buff significantly (40 rounds per magazine); also, it receives much faster-firing speed, with very low recoil and the screen doesn't shake at all. It features a charging bar like other Anti-Zombie Weapons and when fully charged, pressing RMB will activate the Laser Blaster Module that opens up the gun's barrel and discharge a powerful Laser Beam, dealing massive damage against zombies and it penetrates all foes on its way. Furthermore, the Laser Beam can help you and your teammates heal if pointing the Laser Beam at them, with 4 HP per shot.
Availability[]
- Available in all CrossFire versions.
Trivia[]
- This is the first Anti-Zombie Gun that doesn't feature an ammo count for its Charged Mode; instead, the Laser Blaster will consume the charging bar itself when used, and when it's emptied, it'll switch back to default mode automatically.
- In reality, M4A1-S Under Tech has an ammo counter of 150/0 in Charged mode, but it's hidden from view. This counter can be seen by playing Shipyard and Battleship (Defense Mode).
- Just like the AK47-Buster, M4A1-S Under Tech can be obtained permanently via the Boss Crate in Boss War. This was likely done to encourage players to farm this mode to try out this gun and then spend money to acquire Upgrade Gems to unlock the Silver and Gold variant. Due to its extremely low drop rate, however, players might have better luck collecting 100 material pieces for this gun by playing Titan Citadel (Nightmare difficulty) to obtain it permanently.
- Unlike the Knight SR-25 Burning Shot, this gun will reload when activating Charged mode, despite not replacing a magazine.
- This gun's laser beam does not reach Atlas in Devastated City nor the Tripod in Shipyard, however, it's able to hit the Phoenix in Final Arena. The extent of the laser can be viewed from the side on maps such as Devastated City or the crash site at Fatal Canyon.
- In CF Philippines, crafting this gun using 100 scruples will result in the icon appears to be M4A1-S Under Tech Zhao Yun laser module icon. This bug hasn't been fixed yet.
Nerf[]
- At one point, the M4A1-S Under Tech was heavily nerfed, mostly for new maps that utilizes Critical Damage feature. The Laser Blaster module now can only trigger crits on the first target, all penetrated targets will only receive normal damage. Its damage is inferior to weapons such as Holy Shotgun, M240B-Tesla Gold, or Transcending Awakening weapons. Following 2021 November update, the M4A1-S Under Tech has been un-nerfed in CF China, returning its stats to its original value. This fix has now been rolled out to all CF servers, making the M4A1-S Under Tech valuable once again.
