Realm

REALM is set in the year 5069 A.D. and Earth is barely holding on against an alien invasion that is determined to leave the planet in ruins. You're Biomech, a souped-up cyborg, and you're Earth's last hope. Through four deadly realms, you'll take on all comers with an arsenal of weapons that includes lasers, heat-seeking missiles, and plasma boomerangs. One unique feature is your character's multi-directional firing capability, which will come in handy when you find yourself surrounded by hostile enemies. If you're successful, the Earth will recover and live to see another day, and if you fail well, failure is not an option in these circumstances!
