From Man Up Time:
In July of 1986, a covert team of special forces led by your brother Ajax were sent into the jungles of South America to investigate an extra-terrestrial object of unknown origin.
They were never heard from again and the mission was buried. Your superiors told you to "drop it," that it was "above your pay grade". Good thing you never listen.
At 0800 hours, a prototype Delta Hawk recon vehicle dropped you into enemy territory. If you want to survive, you can never ever stop running, and never take you finger off the trigger.
Experience the adrenaline shot of your life. Run, jump, and shoot. Did we mention shooting? We didn't call the game "Gun Runner" for nothing. Unload the most wicked, alien-stomping weapons ever to grace this planet.
And when your not running, jumping and shooting, you'll be rocking out HARD to the all-original soundtrack by 8-bit master Syphus. Prepare for ear hole meltage thanks to the heavy-calibur, guitar-driven, Reagan-era chiptunes that'll make you slap your grandmother. Twice.
Best of all, the price of admission to this non-stop action-o-rama ride? Free.
