- Dynamic Action - Considerable refinement of the games engine makes Armored Core: Nexus the most realistic title in the series yet. The players sense of participation has been improved by providing a wider diversity of destructible objects, accentuating variations in speed, enhancing combat-related details, and including a more robust suite of sound effects.
- Open-Ended Assembly - AC unit customization, a core element of all the games in the series, has also been addressed. Players now have access to over 400 different parts that can be used to construct literally millions of different AC designs. Weapons and parts have been completely redesigned from the previous titles and new part types have been added, thereby allowing longtime users to build completely new AC designs.
- Mission Environments - Just as with its predecessors, Armored Core: Nexus offers players complete freedom of movement in a fully 3D polygon space. New to the series is Nexus active mission feature, which takes into consideration a players in-mission actions in order to determine how they advance through the game. This allows the player to become more immersed in the adventure and derive a better sense of cause and effect.
- Multiplayer Options - Quite possibly the series most popular feature, head-to-head multi-play is included with the title and enables up to four players to compete against one another using either i.LINK or for the first time ever LAN.
