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 a concept of 2 of the pieces of graffiti that will be found near special items, breakable walls, and other special things
Is the primary villain a CSS clan?!??!?!
Sorry but that just looks plain bad.
It has pixeled edges, the colour is ugly as it can get, etc.
You need to work on it more to make it look like a real graffiti.
