Armored Core can take some time to get used to, but the process of building up one's mech and taking on a surprisingly rich variety of battles with technical and narrative depth make this a must-play experience.
After Earth survives a catastrophic war, corporations soon come to power (Chrome and Murakumo Millennium). Inter-corporate war between them provides opportunities for mercenaries called Ravens to fulfill jobs using powerful and highly customizable mechs called Armored Cores.
The player can either play single-player missions or do a two-player versus mode. Players may use guns, rockets, lasers, and swords of varying power and ammo during a mission, with the need to balance energy output and weight for max firepower and survival.
Controls seem a bit awkward at first without the analog stick, but managing aiming with L2/R2 and having good strafe controls allow the player to make either careful and deliberate movements or use a ridiculous amount of vertical maneuvering, including advanced techniques such as the "bunny hop".
While the movement controls are something to train for battles, most of the single player's challenge comes from figuring out the best type of mech for challenges and being able to afford the parts. Using up health and ammo incurs extra costs, and debt can prevent the player from buying new parts. This encourages the player to save often and practice missions until powerful radar and lock-on, high energy output (and energy weaponry), and some helpful guns (read: the chaingun) will turn the player's Armored Core into a killing machine.
Missions can be fairly massive in terms of space, with large fields, vertical shafts, blimps, seaside bases, abandoned facilities, test arenas, cities, and so much more bring this cyberpunk world to life. Graphics are also surprisingly varied for a 1997 3D game, with no attempt at rendering human models (mechs look far better with primitive 3D rendering). Music is solid techno that also fits intense cyberpunk battles and will provide a suitable beat for focus. The player can also customize their mech and emblem, resulting in opportunities for fun and colorful creativity amidst the serious (if a little drab) designs.
Armored Core is plain impressive for the time it was made, utilizing limited controls in mech combat that works both single and multiplayer, enriched with plenty of gameplay variety and a morally ambiguous storyline that puts the player on either side of a futuristic imperialist war.
