A.R.E.A. is a standalone project based on S.T.A.L.K.E.R. trilogy. The project affects all aspects of the game with no exceptions, improving their quality and diversity. The main goal was to create a more realistic Exclusion Zone, where each trip will be a unique and rough experience.
The more character gets drunk, the harder it is to walk straight.
With the first person view death animation now available it would be fun if the actor would fall a few times and get up (without 100% success of course) sometimes dropping the weapon in the process... :-)
Some thoughts:
Can you make it so the drunkenness kicks in later due to alcohol taking some time to be metabolized?
Can you make the player character pass out or throw up from drinking too much?
Yes, it is possible.
