What would be the best system for a The Purge game?

With options to play as a group of Purgers trying to do as much Purging as possible without getting Purged, or non-Purgers trying to make it through the night, either by getting to a safe space or holing up somewhere

Unisystem,if you're lazy?

I swear to god, you better run the game with a grain of intelligence. Those movies are a wasted concept and full of useless plots.

Shadowrun without the magic or augments.

>all crime is legal
>no looting in any of the movies

D&D 4E because it's about as murderhobo-oriented as an RPG can get.

Unknown Armies without any of the magic, which is easy to do and provided for in the book. Or CoC for that matter. Basically, people can be badasses but it comes at great personal cost to every other aspect of your skillset (CoC) or violence makes you brittle and callous as a human being (UA).

I imagine hackers would spend the year building up to the Purge with programs to break through and mess with bank systems, especially in response to upgrading security. They could be as unsubtle as they liked about the stealing and it would be fine, legal millions.
