A stand-alone expansion to last year's Far Cry 3, Blood Dragon uses its predecessor's free-roaming exploration, stealth and shooting mechanics as a vehicle to tell a different story, one permeated by a 1980's direct-to-video B-movie vibe.
Somewhere "in the near future, at the end of the 20th century", you play Sergeant Rex Power Colt, a cyber-commando sent by helicopter to infiltrate an island held by enemy cyborg forces.
Aiding you on your mission is Spider, a fellow cyber-soldier, a prankster who activates a series of mostly pointless tutorials for you to do - press "A" to demonstrate you can read - upon landing.
Even if you have never played a Far Cry game, Blood Dragon's introductory mission does a good job of teaching you the basics. Rex has access to four main weapons, including a sniper rifle and a handful of explosives. He can also track enemy movements with his Cyber Eye.
Perhaps the handiest weapon in his arsenal is the 20-sided die, of which you apparently have an unlimited supply. They can be used to distract enemy cyborgs while you sneak up on them to perform stealth kills.
After a brief introductory mission, Rex and Spider are captured, and the game reveals its doomsday scenario.
Colonel Sloan, an elite soldier who has gone rogue, has engineered a breed of raptor-like blood dragons and is planning to launch missiles that would multiply them manyfold.
Spider is killed in action, but Rex escapes, thanks to Dr Darling, Sloan's disillusioned lead scientist. From that point, you are free to explore the entire island and capture garrisons, or simply head to a marker indicated on the map to begin the next story mission.
There are rewards for capturing garrisons. Each one you capture serves as a new fast-travel point for Rex to teleport to, but also opens up hostage rescue and hunting missions, side quests that will unlock weapon upgrades.
