If you’re a fan of classic arcade cabinets from the 1970s and 1980s, you’ll have a blast with XInvaders 3D. The game uses line graphics (like the classic game Asteroids), and puts a fresh spin on Space Invaders. The 3D rendering makes the aliens move progressively closer to you, and you move in four directions to line up your shots. It’s good, clean, retro fun. Move using the cursor keys and fire by pressing the spacebar.
To install XInvaders 3D, use
sudo apt-get install xinv3d
XInvaders 3D installs into the Other category in your Programs menu.
