Captain Blood on the Commodore 64 is a surreal open-ended space adventure where you play Bob Morlock—“Captain Blood”—a game designer sucked into his own sci-fi universe and accidentally cloned 30 times, now dying as his “vital fluid” is spread among the last five rogue duplicates he must hunt down. From the bridge of your living starship, the Ark, you hyperspace between planets, launch biomechanical probes to their surfaces, and then use the icon-based UPCOM system—about 150 pictograms representing concepts—to communicate with wildly different alien species and coax from them coordinates and clues to the clones’ whereabouts. As time passes, Blood’s failing health is reflected in the increasingly shaky on-screen cursor, making control itself harder until you manage to track, teleport, and disintegrate a clone to buy a little more time, giving this cult C64 port its distinctive mix of atmospheric space-roaming, cryptic alien diplomacy, and looming body-horror countdown.
