Just finished the DLC now and for 12 bucks I think the DLCs are excellent. Not worth 40 bucks but definitely worth it on sale.

The double marauder encounters were incredibly annoying and some platform/puzzle segments were pretty unclear on where you need to go. Having to add lengthy cutscenes so people know where to go sort of should tell them that the level design is not up to spec. But overall very enjoyable, thanks for the recommendation!
