What is dead island vs dead island riptide?

Dead Island and Dead Island Riptide are two first-person action role-playing survival horror video games developed by Techland and published by Deep Silver.

Dead Island takes place on the fictional island of Banoi, which is overrun by zombies. The four playable characters, a former football star, a hotel receptionist, a rapper, and an ex-cop, are immune to the virus that causes the zombie outbreak and must fight to survive and uncover the truth behind the epidemic.

Dead Island Riptide takes place immediately after the events of the first game, with the survivors escaping Banoi on a military ship and then becoming stranded on the island of Palanai. The game features the same four playable characters from the first game, as well as a new playable fifth character, and introduces new weather conditions, such as monsoon rains and flooding.

Both games feature a large open-world environment where players can complete quests, upgrade their skills and weapons, and fight zombies in melee combat. Dead Island Riptide adds a new hub defense gameplay mode where players must defend their safe house from zombie attacks.

Overall, Dead Island Riptide is considered a continuation of the first game, with similar gameplay and mechanics, but with added features and improvements.
