In Reality Check you are actually playing as a player who got pulled into the world of Half Life 2 and now has to find his way through Improbability Zones, Combine Assaults, and even defeat the person that caused the improbability zones in the first place.
This is the first Improbability Ability you will get in the game. it is known as the Digiblade due to how it is made from Digital Data inside the Thumb Drive.
Is this the idea for a weapon or what? It looks like you're showing concept "art" for a USB...... sword?
