Wait for More Details
We know half of the Call of Duty: Infinite Warfare DLC details now that Sabotage is out and the Continuum Infinite Warfare DLC 2 map pack is announced. This helps us know what to expect from the remaining two, but we still don't know how good the second set of maps will be.
There are two confirmed Map packs and thus a theme. You can expect three new maps and one re-imagined map with each map pack. It's unlikely that they will change this formula going forward.
We'll see videos and gameplay of these new maps soon, and more information about the second Zombies experience.
Expect to learn more about Call of Duty: Infinite Warfare DLC map packs in the June at E3 when we should see a teaser about the third Call of Duty: Infinite Warfare DLC map pack.
