Combine: Dead Island Riptide

someone didn't check the new games tab ... Dead Island Riptipe and this dupe need to merge

Oops, searched for it and couldn't find anything so that's why I made it, my bad. Yup, combine please!

@Ursus_Veritas: you need to check the Games -> Newest page. If the game page has no text in the main field it won't show up in the search which is a pain during announcement season.

@DeF: Done.
