This update of Tuesday, April 28, 2020 will allow you to do a rather intelligent thing: you will be able to mix your blueprints (or plans for non-English speakers) of the same weapon in order to create a spade plan. The maneuver does not work with plans of several different weapons.
A new weapon is also available. An LMG responding to the sweet name of: MK9 Bruen LMG. This weapon has a large capacity magazine while doing consequential damage. This new LMG can be unlocked by purchasing the "Encryption" pack or by performing challenges available in the weapons menu. Legendary plans are also unlockable by performing challenges.
The other big news concerns the mode Warzone. Indeed, a new contract is coming: the "Most Wanted" contract. The concept is very simple: you are one of the most wanted men of the level. And that by all the teams. If you survive, your dead crew will be brought back to life without spending a single penny. Convenient.
In bulk, there are also skins and camouflage intended for weapons and operators. A double XP weekend of weapons, experience and battlepass is planned for May 1st.
Call of Duty Modern Warfare is available on PS4, Xbox One and PC.
