New bionic enhancements include abilities such as hacking data terminals, a powerful uppercut, and firing grenades.

The game's plot revolves around a dictator named General Sabio and a missing commander from Spencer's organization, Colonel Brubaker.

The protagonist is equipped with a bionic arm that can be used to grapple onto scenery, allowing the player to ascend or to swing to otherwise unreachable areas.

[2] Veteran players who've become accustomed to the glitchy swing mechanics of prior entries will be relieved, or frustrated, to know they'll need new strategies for completing some of the challenge rooms, most notably making use of the spike pits in order to progress.

These include the ability to jump and maneuver known as Death From Above in which the player slams into the ground upon landing from a fall, causing a shockwave to affect nearby enemies.

Components include a grenade launcher attachment for the bionic arm and a passive heath regeneration ability.

[7][8] Absent from Bionic Commando Rearmed 2 are top-down levels, which in its predecessor symbolized an enemy attack while en route to a location.

[4] In the game, a dictator named General Sabio from the Papagayan Islands threatens to attack the FSA, protagonist Rad Spencer's organization.

[1] En route to Brubaker's last known location Spencer receives a communication from Mag, one of the team leaders, informing him that "something huge" had attacked them, taken her partner McNamara's bionic arm, and forced them to separate.

After disabling the robot, Spencer contacts FSA headquarters to inform them of the situation and the possible demise of Brubaker.

He is then contacted by McNamara, one of his remaining team, who struggles to tell Spencer that he must find and disable missiles armed by General Sabio.

[1] Upon finding Brubaker's signal, Spencer is knocked unconscious by poison gas while contacting Super Joe.

Inside he finds Brubaker, equipped with the bionic legs and arm from Spencer's teammates Wilcox and McNamara.

The player also learns that Super Joe placed the weight of the conflict on Spencer, something that would later drive him to his villainous ways in the future.

[4] The protagonist, Rad Spencer, received a visual redesign for the sequel to tie in the years between Rearmed and the 2009 3D game.

[16] Of his position with Fatshark, Viklund remarked, "They were taking over things mid-project and I worked as a creative advisor during the hand-over to tell them what they were looking at.

Producer Ray Jimenez stated that the reason for this was that the developers "wanted to concentrate on the actual game itself rather than adding new features to it.

Bäckström further stated that coop will feature modified gameplay, requiring players to work together to defeat level bosses.

[17] In an interview with Gamereactor, Robert Bäckström stated that although he did not know a definite release date, the developers had completed the game as of December 2010.

[16] Viklund cited games on the Nintendo Entertainment System as influences for Rearmed 2's music, including the Mega Man series, DuckTales, and Gun.Smoke.

A contest was held from July 16, 2010, to August 11, 2010, allowing fans to remix an 8-bit Bionic Commando track for inclusion in the game.

[37] IGN's Daemon Hatfield gave the game a mediocre score and stated it doesn't feel as special as the original Rearmed.

"[10] GameSpot's Tom McShea gave the game a poor review, criticizing unresponsive controls and cheap deaths.
