Season 4 Reloaded is live in Call of Duty: Modern Warfare 2 and Warzone 2. This mid-season update is themed around a collaboration with Amazon Prime's The Boys television series, which includes the new Diabolical camo challenge event. Here's how to unlock all the new rewards.

How to complete the Diabolical camo challenge event

　　The Diabolical camo challenge event is available from now until the end of the season, and it will earn you two unique and universal weapon camos. The first camo you'll unlock is a light gray The Boys' Vought-themed gray camouflage, but completing them all will earn you a red Diabolical camo.

　　Here are all the Diabolical Camo Challenges:

　　Assault Rifles: Get 50 operator headshotsBattle Rifles: Get 25 operator kills from behindSMGs: Get 250 operator killsShotguns: Get 30 operator kills while proneLMGs: Get 30 operator kills while using a suppressorMarksman Rifles: Get 30 operator kills while mountedSniper Rifles: Get 3 kills without dying 10 timesSidearms: Get 50 enemy longshot killsLauncher: Get 40 operator killsMelee: Get 30 enemy killsEach of these challenges must be done while using a weapon from its related category--meaning for the launcher challenge, you must get 40 operator kills with any of the rocket launchers, and the shotgun challenge must be completed using a shotgun of your choice.

General tips

　　You'll also want to choose your map and mode wisely for these. The many challenges requiring operator kills will be best completed on a small map playlist like Shipment, while longshots with pistols will need to be on maps a bit larger than Shipment, so you'll want to pick one of the standard playlists.

　　Completing all 10 event challenges unlocks the red Diabolical camo, and an event-themed weapon charm.

　　Season 4 Reloaded also includes a brand-new weapon to unlock, and here's our full guide on how to unlock the MX Guardian shotgun in Modern Warfare 2 and Warzone 2.
