The barriers are digital defense mechanisms set to keep any intruders out of a network. In cyberspace, they take the appearance of translucent green squares with surfaces resembling circuit boards.
The barriers serve two primary purposes. In the first case, they act as walls that will suddenly emerge and barricade passages to prevent the player from moving forward. In the second case, they act as platforms for the player to stand on, allowing travel across bottomless pits. In either case, the barriers can be destroyed after a certain number of hits with any attack. Upon taking damage, these barriers will gradually turn yellow, then red before shattering. It is ideal to only destroy those that block the player's path, as destroying the platform variants will only give trouble for the player.
