The "biggest ever update" for Gears of War 4 is slated to arrive on June 6. The "Rise of the Horde" update for the game will be free to everyone and will add in 15 new skills, level 6 skills, two new difficulty levels, and 20 new achievements.
Both the new and existing Skills can now be taken to Level 6, making them even stronger than ever before! The new 15 skills arriving in Rise of the Horde focus on providing new ways to specialize the way you play your Class.

These were just some of the details on the new skills. I didn't even show off the new difficulty levels, the new maps, the new achievements, new card packs, ranked crossplay, additional rewards for new players, or even touch upon how they're offering up a free trial of the game to everyone.
