Armored Core for Sony PlayStation 1 (PS1)
You take on the role of a mercenary pilot of a large robot who can be hired out for missions varying from straight-out assaults and guarding convoys to bug extermination and classic one-on-one mech duels. These all take place within or above a number of terrains, such as underground installations, desert bases, downtown cityscapes, helicarriers up in the clouds, and space stations up even higher still. Nearly all are knee-deep in fun, and they culminate in a super hard final stage in which the developers at From Software really used their game designing skills for evil: You must pilot your mech to the top of a skyscraper-high complex via 3D floating cubes armed with guns mounted on both top and bottom - and that's just the tip of the iceberg. Almost as charming as the gameplay are the upgradable options for the mech, which you'll be able to afford after successfully completing a few operations with the rig you start out with. These options include different functioning heads, cores (or chest units, thus the game's name), arms, legs, arm weapons, back weapons, radar, boosters, generators, chipsets, and more, all of which must be balanced out with armor class, weight, energy drain, and several other functions. A test stage is available to test out your mech after it has been assembled in the garage, to make sure that you're happy with the new setup. If you're not, the shop buys back used parts at full price. Different patterns and a custom palette are also available to paint your wagon with, allowing for everything from camo to plaid to your own personal shades of neon.
