Avengers Initiative is a standalone game for mobile devices, primarily running Apple's iOS and Google's Android operating systems.
The game is connected to Marvel: Avengers Alliance (MAA) through Marvel XP, and is the first game other than MAA to use Marvel XP. The inter-connectivity allows for a shared reward system, which is based on Marvel XP Awards.
