I played Modern Warfare 4 early! Here are my major takeaways and a video showing 4 brand new maps.
✅New campaign sounds like a really fresh approach. South Korea is being invaded by North Korea and it's allies, you play an American solider embedded with South Korean soldiers
✅Guns are fundamentally changing with a new "weapons first technology called Ballistic Authority. Bloom is removed completely. Wherever the barrel/reticle is aiming, that's the trajectory of the bullet, among other big changes to visual feedback, visibility, more realistic weapons handling, etc.
✅12 6v6 maps day one, with a few other maps for larger game modes, plus a new dynamic map for Gunfight modes that changes layout in between rounds
✅Omni-movement is GONE, but mantling, sliding and overall movement is faster and more responsive. You can go into a slide straight from a mantle, you can hang on ledges, shimmy on ledges and peak over with your gun
✅When you max out a gun, you unlock its Apex Attachment. This completely changes how a gun works, or adds a secondary fire. For example, explosive shells for a shotgun, or throwing knives attached to the frame of a rifle, etc. Really cool addition.
✅DMZ IS BACK! But this time, it's a major focus and not a beta. Described as a living sandbox set in a massive conflict zone. Players can negotiate, team up and betray (similar to Arc Raiders)
Overall, I think the success of Modern Warfare 4 lives or dies with the new DMZ mode. If this mode is well received, it could bring old players back and introduce non-cod players to the game and has the potential to get Call of Duty in a much better place.
