As with previous Armored Core games, players in Last Raven are pilots of mech robots called Armored Cores. Players can take on over 70 missions that play out over a 24-hour period.[1] Completed missions provide the player with credits to spend on parts and weapons, and can influence the availability of subsequent missions. The 24-hour period incrementally moves forward with each mission, and mission choices can dictate the narrative ending the player receives.[2]
Customization is identical to previous entries. Players start the game with 300,000 credits and a basic Armored Core. They can alter the mech with hundreds of parts and weapons, each of which can change the player's gameplay experience.[3] A component damage system allows for parts to be broken individually over the course of a mission, drastically affecting its performance. For example, damaging its legs crippled its movement, while damaging its arms removes its ability to use hand-held weapons.
