Ziggurat Interactive, the publisher best known for preserving and remastering many forgotten gaming gems, is giving away 500 steam codes over the next two weeks.

The special giveaway, called “Stay Inside & Play Inside,” is a 10 day online sweepstakes. Ziggurat is giving away 50 codes every day, starting today, for 8 of their most popular games. To enter, all you need to do is visit their website and sign up for their mailing list from the contest portal.

Ziggurat Interactive is in the business of preserving the oldest and rarest games, remastering them, and making them available once again to PC players. Their games aren’t necessarily household names anymore, but at the time they were released (as far back as the 1980s) they were some of the most popular games on the market.

The contest includes keys for 8 games: Central Intelligence, Slave Zero, Deadly Dozen, Superhero League of Hoboken, Darklands, Nam, Marco Polo, and Mission Control.
