The Dead Island series is the go-to franchise for first-person zombie slaying. Right now, Steam has everything involving the Dead Island series on sale. This means that if you just want the original game’s Game of the Year Edition, it will only set you back $4.99. However, since Riptide is that price, the best overall value is the franchise pack for 75% off. That takes everything down to $7.49, and it’s a far better value than getting the included items on their own. I enjoyed the first game quite a bit, and at only $2.50 more, you might as well get the follow-up in Riptide as well.
