Upping the Odds for Marvin is the name of a series of Team Quests in Dead Island: Riptide, given to the player by Marvin. The Hero must find and retrieve a series of items for Marvin so that he can upgrade his weapon. The Hero will be rewarded with XP and a number of pieces of Exploding Meat.
Unlike other Team members, Marvin only has two Team Quests available to the Hero, completely skipping Upping the Odds for Marvin I. Because of this Marvin starts off with an upgraded weapon: a Cane Knife with the Lightning Mod installed.
Upping the Odds for Marvin II[]
The Hero must retrieve 7 Nails and give them to Marvin. In exchange they will receive a moderate amount (3-star rating) of XP and 7 pieces of Exploding Meat.
After completing this quest, Marvin will upgrade his weapon to an Uncommon Meat Mallet with the Nail'd Mod installed.
Upping the Odds for Marvin III[]
The Hero must retrieve 3 Lightweight Frames and give them to Marvin. In exchange they will receive a high amount (4-star rating) of XP and 9 pieces of Exploding Meat.
After completing this quest, Marvin will upgrade his weapon to a Unique Heavy Baton with the Nuts & Bolts Mod installed.
