System Invaders

Game Summary Pitch

System Invaders is a fixed shooter in which players “slingshoot” themselves against the invading viruses to destroy them.

Gameplay Overview

The player controls Barry the Bear antivirus to help him defeat the evil viruses attempting to invade the system where he lives.

Barry can grow stronger and faster by upgrading his software with in-game currency that is dropped by the viruses.

The viruses will get progressively stronger related to the number of waves the player has cleared.

Theme Interpretation (You are the weapon)

Within the context of a mashup between space invaders and angry birds, rather than shooting the “invaders” you smash into them by aiming at them or strategically bouncing off walls or other enemies, making you the weapon in the literal fashion.

The Player

The player character is Barry the Bear Antivirus, my goal with his design was a callback to Panda Antivirus and his name is a homophonic pun (rely on homophones: words that sound the same but have different meanings) since Barry sounds like Bear-y and he’s a bear.
