Intravenous is a stealth/action game with heavy emphasis on stealth. It's a love letter to the early Splinter Cell games, and a condensation of various gameplay ideas I've had rolling around in my head. Most importantly it is a game I would put tens of hours into. The goal is to make a challenging, fun, and satisfying stealth game.
Features
Old-school stealth. Your visibility depends on how well-lit the environment is, and every step you take makes noise.
Teeth-grinding action. Fun stealth gameplay does not exclude fun gunplay. Intravenous is meticulously designed to offer stealth for those looking for it, as well as no-brakes gunplay to those itching for a gunfight.
Reactive AI. Your enemies will do more than just rush straight at you. If they've found a dead body they will alert their friends in hopes of finding you. If they hear you sneaking about, they will investigate. If they see you, they will open fire. If they're unarmed, they will try to find their friends and warn them of you.
Capable enemies. Enemies take cover during gunfights, use flashlights in darkness, and radio in suspicious activity. Any misstep you make will result in your opponents responding appropriately.
Lots of weapons. Multiple weapons, each with their unique handling. Each works best in a specific situation. You're sure to find your personal favorite here.
Choose your loadout. Pick a rifle, a pistol, and a bulletproof vest to be ready for combat, or just a pistol and naught else, to be quick, agile, and silent- ready for improvisation.
Adapt to your surroundings. Shoot lights out, crawl through vent shafts, flip circuit breakers off, throw bottles to distract your foes, lockpick doors to find alternative ways in - or simply shoot the door lock out, and go in guns-blazing.
