Limiter Release
Releasing the Limiter on the unit grants you infinite ammo on most, if not all, of its attacks. A selected number of moves are not affected by the Limiter Release. To get it, clear the game once, fully upgrade a unit and max out its EXP. The "Limiter Release" upgrade will then show up in the upgrade screen.

Post-game Unlockables
Clearing the game once unlocks some features, such as New Game + and EX Missions. The 4 EX Missions in this game puts the player against much more difficult challenges than any Mission in the game, such as multiple boss-level enemies, thousands of grunt enemies, and a huge group of the same strong enemy unit, while the VS Missions pit players against a single playable strong enemy/group in each fight.

EX Missions - In the New Game +, clear the Missions from the other route on both route splits. EX Missions will then become available in Free Missions mode.

New Game + - Load the cleared save. Player gets to play through the game again while retaining all previous units and upgrades.

Real Ace Difficulty - Automatically becomes available under "Options" on New Game +. Clear this mode to prove yourself as an ACE!

VS Missions - Certain VS Missions in Free Missions mode are only unlocked after clearing the game once.
