Invention 4

In "Invention 4", players take on the role of Dorian Stealth, a mercenary tasked with rescuing Cassie Jefferson in 2043. A zombie virus has devastated humanity, forcing survivors into basements to evade disease and hunger. Players must navigate through perilous environments, engaging in intense shootouts against swarms of undead while solving puzzles to progress.

The game features dynamic 3D shooting action mixed with exploration elements and problem-solving challenges. Dorian is equipped with a variety of weapons: a knife for close combat, a shotgun for medium range, a grenade launcher capable of clearing multiple enemies at once, and a Kalashnikov machine gun as a versatile but limited ammunition option.

Each weapon requires strategic use to overcome the hordes. The knife is effective in tight spaces and against lone targets, while the shotgun offers rapid fire potential that necessitates reloading after each shot. The grenade launcher provides explosive firepower suitable for area control, but at the cost of ammo. Meanwhile, the Kalashnikov acts as a jack-of-all-trades, though with scarce ammo reserves.

The core gameplay revolves around utilizing these weapons effectively to defeat both small groups and powerful boss monsters. Players will face off against vast numbers of zombies while relying on their wits and weapon choices to emerge victorious in each challenge.
