The graphics were okay, a decent 7/10.
The voice acting... sounded nothing like the spy in the game. He sounded like a drunk man with a stick up his ass trying to impersonate Pepe' Le Pew. Oh, and why did the engineer sound like one of those red-necks from Blue-Collar TV. I give your voice acting a horrid 1/10.
Similarities to the game. Where do I begin... The spy has a striped tie, along with patches on his suit. The dispenser doesn't dispense those plus signs unless its healing someone. The spy's cig is on the wrong side of his face. etc... a generous 4/10.
