Armored Core: For Answer is a 2008 vehicular combat game developed by FromSoftware and published by Ubisoft for the PlayStation 3 and Xbox 360. It is the 13th installment in the mecha-based Armored Core series, the game is the direct sequel to Armored Core 4. AC customization has been changed from the previous Armored Core title, with a new interface and many new parts not found in Armored Core 4. Online mode returns with a new co-operative mode alongside the player versus mode. Gameplay enhancements included a power increase for both Quick Boost and Over Boost, as well as an auxiliary high-speed booster, which is known as the Vanguard Over Booster (VOB). Another new feature in the game is the Assault Armor attack that becomes available by equipping certain Over boost parts. This attack uses up all available Primal Armor (PA) that the AC has and generates a huge blast consisting of Kojima particles (highly reactive particles) that destroys or damages all objects surrounding the AC. However, this also leaves the AC vulnerable because not only will the AC lose its PA, it will also not regenerate for a few seconds. Laser blades are deadlier because of the revamped laser blade attack. Once the blade has acquired a lock-on, the AC will instantly rush to the target, traveling a great distance to use the laser blade. All parts carried over from the previous game have had their parameters altered, much like the transition between previous series installments Silent Line and Nexus. The on-screen HUD can now be changed to any of 20 colors. There are now 442 FRS tuning points available to unlock, which is an increase from the 300 (PS3) and 337 (Xbox 360) FRS points available in AC4. Maps are much larger and more detailed including environmental damage such as collapsing buildings. The game is also the second in the series (after Last Raven) to feature multiple endings, with three different possible plot branches available depending on your actions and decisions in the game.
