Seicross, known as Sector Zone[a] in Japan, is a shooter arcade game developed and released by Nichibutsu in Japan and North America. Despite the original arcade game being titled Sector Zone, Nichibutsu later ported it to the Famicom as Seicross (セクロス). This port was also published in North America for the Nintendo Entertainment System by FCI.
During the game play of Seicross, the player rides a gliding motorcycle-like vehicle, bumping other riders, collecting power modules and collecting blue people who are stranded. A second area removes the riders and adds rough terrain, while the final leg features a battle with one or more Dinosaur Tanks, which launch their heads when destroyed. The sequence repeats infinitely, getting progressively difficult and changing backgrounds.
Gene Lewin of Play Meter rated the arcade game 8 out of 10, stating it "is challenging as well as fun to play."
