The game itself is beautifully rendered, especially the character models who are based on classic and modern Marvel comics. Each character begins with two special attacks and they can unlock more as they level up. These special attacks come with cooldowns that notify you when they can be used. Other team members are swapped in by tapping on their portraits and once a level you can 'summon' one character from another player to help you. In-between missions you will be looking to improve your characters by upgrading their gear and adding any ISO-8 you gain to enhance their skills.
