Our take on Invention 4

Weapon choice carries a resource trade-off: the shotgun needs reloading, while Kalashnikov ammunition is extremely limited. The grenade launcher can affect groups, but each weapon’s role narrows its use in different encounters.

What is Invention 4?

Set in 2043, Invention 4 follows mercenary Dorian Stealth, who must rescue hacker Cassie Jefferson and deliver her to the Investment Corp.

Humanity is hiding in basements while a zombie virus causes hunger and disease. The game combines 3D shooting with quest and puzzle elements. Dorian carries a knife for close-range combat, a shotgun for medium-range attacks, a grenade launcher for large explosions, and a Kalashnikov as a general-purpose weapon. The shotgun requires reloading, while Kalashnikov ammunition is extremely limited. Players use the weapons’ different tactical roles against groups of zombies and bosses during the rescue mission.
