Marvel's Avengers is a third-person, action-adventure game that combines an original, cinematic story with single-player and co-operative gameplay. The game features a unique combat system chaining attacks, dodges, abilities, skills and elements to succeed a combat phase. The game can be played offline as a single-player experience or online with up to four people during certain aspects of the game.[2] The game will feature customization options including abilities and costumes, which can be upgraded using a skill tree. Costumes have been sourced from "all corners of the Marvel universe" and can be earned in-game or bought separately as DLC.[3][4] Players will also be able to receive free updates containing new regions and characters.
