Onslaught | Black Ops 3

Onslaught is a wave-based gametype where you play as a remaining survivor of a failed strike team. You must hold out agains the robotic onslaught for as long as possible.

The gamemode allows ten failures until the map ends. If you survive to Wave 25, then the robotic onslaught will have been crushed and you will win.

The mod has been designed as a cooperative gamemode, akin to Zombies. You can play it solo, or with up to 18 players.

To play, just load the mod and in the Custom Games menu, under Set Game Mode, select Onslaught. Then pick your chosen map and start. You'll need to scroll down in the Set Game Mode menu to see the option.

All stock maps (including DLC) are supported, as is any custom map that supports TDM.

The basic enemy is the G.I. Unit. These robots will attempt to rush you down whenever possible. The bulk of each wave is made up of these. Occassionaly they will throw Flashbangs to disorient a player.

Other than the robots, there are various other hazards that will occur during each wave:

Missile Barrage
A barrage of missiles are fired in all outdoor quarters. Seek cover inside to survive.

Bomb Run
A targeted bomb will be dropped at a player's location five seconds after the warning.

Talon
A Talon will enter the battlefield and attempt to kill any players that approach it. Quick and deadly.

Cerberus
A Cerberus will enter the battlefield and attempt to kill any players it finds. Slow and deadly.

R.A.P.S
Up to five R.A.P.S will enter the battlefield and attempt to kill any players it finds. Fast and spiky.

VTOL
Used to transport the Combat Robots, Cerberus and R.A.P.S. These are unkillable, but will not attack you.

At the start of each wave there is a chance a mutator will be applied. These change various limits during the wave, and can make a wave easier or harder.

Grenade Spam
Robots are far more likely to throw Frags.

Sticky
Robots will now throw Sticky grenades.

Hellfire
Missiles are more likely to appear during a wave.

Bombing Season
Bomb Runs are more likely to appear during a wave.

Swarming
Talons are more likely to appear during a wave.

Rolling Steel
Cerberus are more likely to appear during a wave.

Balls of Iron
R.A.P.S are more likely to appear during a wave.

Scavenger
Players earn twice as much Salvage as normal from kills during a wave.

Moon Boots
Player gravity is 25% of normal gravity during a wave.

Hydraulic Overload
Robots can move between 110% and 135% their normal movespeed during a wave.

In Onslaught, your helmet has been outfitted with a cybernetic enhancement called V.I.S.O.R. This allows you to exchange salvage you collect for useful goods and beneficial effects.

V.I.S.O.R is split into several categories, which are:

• General - This contains options to refill your primary ammunition, and your equipment ammunition.
  
• Weaponry - This allows you to purchase any weapon in the game in exchange for salvage.
  
• Attachments - This allows you to swap your current attachment setup on your gun ingame.
  
• Optics - This allows you to swap your current optic attachment on your gun ingame.
  
• Boons - Boons are useful effects you can buy with varying durations.
  
• World - This contains options that spawn ingame objects, such as a barricade.
  
• Stats - This displays your personal stats for the current game.

If you want to play with bots, use the /add_bots command. For example, /add_bots 8 will add eight bots.
