The Disc Blade Gun is a weapon manufactured by Gadgetron in Up Your Arsenal. It fires a large rotating saw blade-like disc that deal heavy damage to enemies. It is theorized to be the precursor to the Buzz Blades in Tools of Destruction, Quest For Booty, Clock Blockers, and Full Frontal Assault. It is also very similar to the Prog Blades in Into The Nether Regions.

It can be purchased upon reaching Obani Gemini for 175,000 bolts, or 157,000 if you've beaten R&C1 beforehand. At Level 5, it upgrades into the Multi-Disc Gun. In challenge mode, it can be upgraded to the Mega Multi-Disc Gun for 500,000 bolts. From there it can be upgraded all the way to the Omega Multi-Disc Gun at Level 8.

At V1, The Disc Blade Gun fires a homing Disc that upon impact with an enemy, explodes for 500 damage. The explosion is small, and will rarely hit other enemies.

At V2, while still exploding on hit, the Disc now has a Durability of 2, and damage increases to 600. This means if it hits an enemy or a wall, it'll retarget onto another enemy, hitting them again and causing more destruction.

At V3, You can now hold to autofire, and alongside of a 15% attack speed boost, The discs have a durability of 3, and a damage per hit of 1400.

At V4, You can now lock onto enemies to see their health, and Discs gain a Durability of 4. Damage increases to 2400, and Explosion Radius is increased.

At V5, The Disc Blade Gun transforms into the Multi-Disc Gun, which now increases blade damage to 3600. Upon hitting a wall or an enemy, the Discs now split into 2 more discs on hit, creating up to a total of 16 discs per shot.

At V6, Discs now have faster and better tracking, and the radius of the explosion when a Disc hits is now tripled in size. Damage is increased to 4400.

At V7, Attack speed is increased by 50%, which slowly ramps up over a period of 3 seconds while holding the fire button. Discs have faster projectile speed. Damage is increased to 5600.

At V8, Discs now start firing miniature Discs, which can on their own split into 4 more Discs. Discs can also now hit other Discs mid air to explode and create more Discs. Damage is increased to 8400.

The Disc Blade Gun is a red and dark grey weapon, with a left-hand grip, which gains more detail at levels 3 and 4. It has a single slot from which discs are fired. The Multi-Disc Gun has a barrel with two slots instead. Like most other weapons, it gains additional details with more levels.
