Introduction

Eterno Inferno is a single-player 2D action shooter from developer sandrosp5 that runs directly in a browser and needs no installation. Its stages are packed with enemies, and the action keeps pushing forward through waves of foes, doors to open and large bosses to defeat. The arsenal offers nine weapons, from a pistol to a railgun, flamethrower, laser sword, rocket launcher and sniper rifle. Levelling up earns upgrades, while dash, ghost mode, bombs and a nuke add more ways to survive. There are three modes: Campaign, Infinite, where the aim is to survive as long as possible and beat a personal record, and Boss Rush, which features bosses only. Easy, Medium, Hard and Extreme difficulty settings are available. The game works on desktop and on mobile in landscape orientation, and it is available in Portuguese, English and Spanish. The developer notes that it was made with the help of AI. For players who want immediate, fast-paced arcade combat with plenty of weapons and large boss encounters, Eterno Inferno is built to deliver that in a browser tab.
