If you dug zombie RPG Dead Island as we did, you may be happy to learn Dead Island: Riptide is in development, a "new entry" in what is now a series.
Very little is known about it right now. All I can really say is it's planned for consoles and PC and is being developed by Techland again. Whether or not it'll even be a full-on sequel or not remains to be seen.
Whatever the case, hopefully publisher Deep Silver gives this one all the time it needs -- we wouldn't want to see Riptide launching in rough shape as it did before, particularly on PC.
We'll have more on this late summer.
