The mechanics of Armored Core: Nexus continues with many of the franchise's conventions. Players pilot large mech robots called Armored Cores and are hired as mercenaries for objective-based missions.[1] Armored Cores are highly modular and can be customized with hundreds of parts and items.[2] Money is earned through missions and can be used to purchase customization options, but any expenses incurred through a mission are automatically deducted from the player's income.[1]
Mouse support allows for players to create emblems and navigate menus.[3] The control scheme of Nexus has been updated to include support for dual analog sticks, a first for the franchise.[2]
Nexus is split into two discs. The first, Evolution, is the main game and story sequel to Silent Line.[4] The second disc, Revolution, contains updated missions from earlier titles in the franchise that can be played using Armored Cores from Nexus.[1]
Like previous games, Nexus includes several multiplayer options. Split-screen modes and I-Link multiplayer connectivity return, allowing for 2 player head-to-head combat. A new addition is a LAN multiplayer mode that allows up to 4 players to connect and fight each other.[4]
