Hard Corps: Uprising is a run and gun game developed by Arc System Works and published by Konami for the Xbox 360 and the PlayStation 3. The game was released digitally on Xbox Live Arcade on February 16, 2011 and on the PlayStation Network in March 2011. In Hard Corps: Uprising, the player assumes the role of an elite soldier simply called Bahamut, along with other main characters. Konami has added three additional player characters (Sayuri, Harley Daniels, and Leviathan) via downloadable content.

Hard Corps: Uprising is the thirteenth overall installment in the Contra series and serves as a prequel to both the original game and Contra: Hard Corps. Producer Kenji Yamamoto has said that the intention is to "link [the game] to Contra: Hard Corps" and "make [Uprising] into a brand new franchise", taking inspiration from the previous Contra installments.

Hard Corps: Uprising features two main game modes, Rising and Arcade. In Rising Mode, players can collect points throughout levels which are then used to purchase various upgrades and customization for weapons, armor and character abilities. Both modes also feature a health bar, similar to the Japanese release of Contra: Hard Corps, allowing the player to take more than one hit before losing a life. Arcade Mode is a more difficult game mode in which the power-up shops are removed.

Many new moves have been added. The character can dash, dash in mid-air, double-jump and deflect enemy projectiles by bouncing them back. Additional moves can also be purchased in Rising Mode.

Weapons include the standard rifle, the machine gun, the spread shot, the crash gun (shoots arcing grenades), the ripple gun (acts like a force field when sprinting), the heat gun (shoots large blasts of fire), the chain laser (homes in on enemy targets) and the Katana (unleashes a wide arc of energy onto the targets). As in Contra III: The Alien Wars, the player can carry two weapons and switch between them at any time. By collecting the same weapon several times the player will improve its firing rate and power. Other weapon upgrades are available in Rising Mode as well.

Hard Corps: Uprising can be played in local or online 2-player co-op.

In 2613, twenty years before the events of the original Contra, the world is ruled by an empire known as the Commonwealth, under the reign of Tiberius. Neighboring nations have suffered under the Commonwealth's oppression and resistance forces rise across the land. However, so many resistance fighters have fallen to the overwhelming might of the empire, that their strength is now severely diminished. A group of elite soldiers rise through the ranks of the resistance and band together to execute a desperate plan. The leader of this group is the war hero Bahamut.

The game's soundtrack is composed by Daisuke Ishiwatari.
