From the developer

Dark Sector is an intense alien-raid action game set deep inside a hostile, claustrophobic tunnel. Waves of deadly extraterrestrials pour in from the shadows, and survival depends on your firepower and reflexes. Armed with futuristic weapons, you fight your way through relentless attacks as bullets light up the darkness. The rule is simple: the more guns you carry, the easier it becomes to wipe out the alien threat. Stack your arsenal, upgrade your firepower, and turn the tunnel into a storm of shots and explosions.
