Introduction
Alien Arena is a pixel-art, top-down shooter by developer mariussdevv. It drops players into an alien invasion and asks how long they can last. Enemies arrive in waves that grow larger over time, with acid-spitting attackers and charging foes to dodge. Every five rounds, a boss joins the fight. Between rounds, players choose upgrades for their soldier, building a stronger run as the pressure increases. Power-ups add variety during combat, including a shotgun, laser, fire, shield and bombs. The main invasion mode combines waves, bosses and upgrades. There are also boss rush and versus-AI modes, and two players can team up locally on one keyboard. Keyboard and mouse controls cover movement with WASD, aiming and shooting with the mouse, a dash on Space, and pause on P or Esc. The game also offers touch controls on mobile. Its listed language is Spanish (Castilian), and the developer says updates are continuing. Sessions are listed as very short on average, which suits quick arcade breaks.
