What game modes are there?
Story
A cinematic story mode where you witness a narrative of Marvel and Capcom's universes clashing, with the heroic characters seeking to defeat Ultron-Sigma, an evil union of Marvel's Ultron and Capcom's Sigma, both maniacal robots who wish to eradicate all organic life. You'll alternate between watching cutscenes and fighting battles, many of which have special conditions, or are against special minion or boss characters that are exclusive to single-player modes. Note that there is no real point to playing this mode more than once, as you get no benefits for doing so and there are no alternate paths or high scores to attain or experience.

How do you unlock additional colors?
Play matches with the characters you want to unlock them for. These can be either in Arcade mode or in Online battles. Once you unlock a color for a character, it also unlocks it for their alternate costume(s). It only takes about 10 matches to get both extra colors for a character.
How do you unlock additional stages?
Complete the Story mode. This will unlock XGard - Underground Prison, XGard - Bifrost Bridge, Avengers Tower - Lab, Knowmoon - Gravitron Core, Knowmoon - Walkway, Abel City - Sigma's Lab, A.I.M.BRELLA - Laboratory Pathway, and Dark Kingdom - Wastelands. Note: you do not need to watch the cutscenes in order to count as completing the story mode, and they can be skipped even on the first viewing by pressing Start.
How do you disable voice chat?
There is no way to fully disable it permanently, but you can at least mute the volume of incoming voice chat so you can ignore it.
