This is a post showing off most, (but not all) Weapons in Onslaught : extreme combat reborn and Onslaught 2. Most of them have secondary fires and are quite OP… This game feels a lot more fast paced due to the insanely op guns you get.
Weapons:

Plasma Pistol – Your starting weapon. Very weak and is useless most of the time.

Spike Rifle – Shoots nails in a spread… Somewhat useful

Overkill Cannon – Shoots shotgun shells at minigun speed. Very useful for certain enemies…

Spread Rifle – Shoots a spread of AR bullets… Wastes bullet ammo but is more like a shotgun than an AR.

Double Shotgun – Semi Auto Double shotgun that can be tap-fired to fire faster, like the Wolf3d Pistol. Secondary fire shoots Quad shotgun Blasts..

Autoshotgun – An auto shotgun. Secondary fire shoots a quad shotgun Blast.

Lever Action Shotgun – Weakest Shotgun in the game. Has to be reloaded between shots. Secondary fire shoots a double shotgun blast.

Triple Barrel Chaingun – Shoots a Shotgun at minigun speed for a secondary fire…


Assault Rifle – Secondary fire shoots an Armor Peircing Round that Gibs most weak enemies.

Nailbomb – Throw these and they shoot nails everywhere when they explode.

Rocket Chaingun – This chaingun fires minimissles at chaingun speed.

Asskicker Dual Rocket Launcher Backpack – 2 Rocket Launchers mounted on a backpack. Secondary fire shoots tons of missiles at once.

Napalm Cannon – Shoots a spread of flaming Projectiles. Secondary fire shoots them rapid fire.

Gasoline Can – Shoots gasoline on the ground that ignites later into fire.

Flamethrower- Just your standard BBQ.
