DMR (before fix)

[Infinity Ward @InfinityWard]

Thanks for the feedback from yesterday’s Kill Block streams.

We just rolled out a fix for the bugged suppressor that was using the wrong muzzle flash VFX. Additionally, we have reduced muzzle smoke opacity for all weapons for this weekend’s preview sessions.

A clear sight picture is critical to the gameplay experience. Keep the energy coming, we're engaged.

[Infinity Ward @InfinityWard]

@charlieINTEL Seeing #MW4 in the hands of players for the first time has been an exciting milestone for the team.

These are pre-release Alpha builds and are still very much a work in progress. The muzzle flash VFX issue in today's Alpha gameplay is a bug that will be fixed for Beta.

@TheGhostOfHope Wrong (again.)

Gunny is hand crafted by our developers, not AI. It recommends builds based on the attachments you’ve unlocked for each weapon. It helps make quick loadout changes between matches.

Give it a shot in the Beta.

[Infinity Ward @InfinityWard]

@WhiteManReborn We’ve seen the early conversations around visual recoil. The Beta will give players a chance to get hands-on, and we'll be monitoring feedback closely throughout both weekends.

[Infinity Ward @InfinityWard]

@charlieINTEL Kill Block does not have dynamic weather. Sometimes slabs have snow and sometimes they have rain driven by the weather machines in the facility.

[Infinity Ward @InfinityWard]

We're launching Kill Block with Gunfight 3v3 and Gunfight 10v10. Kill Block always starts with a randomized layout. Every 2 rounds, when the loadouts rotate in Gunfight, the map rotates to a brand new layout. This allows each team to play 1 round at each end before the rotation. Once more modes are added to Kill Block in post-launch, each mode will drive if and when the slab reconfiguration occurs throughout a match.

[Infinity Ward @InfinityWard]

At Infinity Ward, authenticity is where we start.

For #MW4 we set out to create the best feeling weapons we've ever made.

Take a look inside our process in episode 5 of From The Ward.

[Call of Duty @CallofDuty]

Welcome to Kill Block: a live-fire arena where modular battlegrounds reconfigure throughout a match, creating hundreds of unique combat layouts.

The right score changes everything.

It builds the tension, shapes the emotion, and gives every moment its weight.
