It's an already wide lake but it sounds like they're really doing what they can to ensure it's deeper than an inch which was easily the weakest part of DL. Beneath the surface it was just very samey and the locations felt too cut and paste especially with the instanced infected zones.
It needs a better modding community too. Would be nice to see community campaigns, weapons and the likes be made instead of being dominated by half-assed parkour maps.
Also, no surprise QTE bullshit.
