When the author himself mentions booze and getting wasted as some of the background of Grezzo 2, a Drinking Game couldn't be more appropriate to add some flavour.
- For newcomers: a shot every time you have to pause the game because of a WTF reaction.
- For those who play the English translation, a sip of beer for every "Blind Idiot" Translation.
- Take a shot every time you hear a blasphemous profanity.
- Take two shots every time you find a broken weapon that doesn't consume any ammo.
- Take a shot every time you find an Improvised Weapon or otherwise a humorous and absurd weapon.
- Take sip of beer every time an enemy explodes in Ludicrous Gibs.
- Take two shots when you die. If you're playing a deathmatch, reduce that to a sip of beer. Seriously.
- If the game crashes, three shots!
