Deep Silver’s first-person shooter Homefront: The Revolution has been building up major steam over the last few months with a live Twitch stream that included a number of online personalities and a lucrative campaign that delved more into the war story revolving around the game, as senior manager of marketing and communications Will Powers previously discussed with us.

Now a new promotion has appeared where gamers can actually win prizes as they unlock more secrets behind the game’s storyline, thanks to the introduction of an interactive map.

By visiting the official Homefront map page, fans can explore across a map of Philadelphia, unlocking new parts of the city and gaining intel on the villainous Korean army that has overtaken the territory. Through a series of mini-games, users can not only unlock more information about the game, but earn additional entries into the sweepstakes, which features prizes from Astro Gaming, Loot Crate, Hyperkin, Razer and Sumo Lounge, as well as copies of the game.

Deep Silver prepared a video that thoroughly explains the promotion, which allows users to earn rewards as they search through the city, including badges and promotions—on top of the prizes that they can win. It’s a unique—and fun—way to get them more drawn into this visceral game world, prompting them to dig a little deeper.

Those who pre-order the game through the site (either via GameStop or EB Games) will also gain access to a special underground subway zone with even more mini-games and videos to partake in.

Homefront: The Revolution arrives for Xbox One, PlayStation 4 and PC on May 17.
