All these DLCs need a bit more content to feel worth it. Mainly, I would suggest Keen add some sort of mini campaign with each DLC. Not centered around the new content, but definitely showcasing it. People don't want gameplay barriers in multiplayer content, but a story mode for single player or small co-op would add a lot more value to each DLC. On that note, a continuing campaign would make a fine DLC series. A campaign with a few hours of gameplay each, with a continuation to the story released each month. If each monthly episode were only $2 each, players joining several months in wouldn't be too daunted by the price tag of catching up. Preferably it should be planned for small group co-op since a story is best shared with friends. Cosmetic features are nice, but something to do with each DLC would be better.
