About Ground Zero Demo

This demo contains Chapter 1 and some of Chapter 2 from the full version of Ground Zero. You will be able to play either route from Chapter 1 (both if you choose to replay the demo). There will also be an 'Very Hard' difficulty mode you can unlock once you complete the demo. Localisation is implemented but not final - so some languages may have some strings missing or other minor errors that will be fixed ahead of launch.

Ground Zero is a retro survival horror set in post-apocalyptic South Korea.

A devastating meteor impact has wiped out South Korea. 2 months later as the dust and lightning storms settle and the air becomes breathable, an elite Korean operative and her Canadian partner are sent to investigate. What waits for them in the foggy remains is more terrifying than they ever could have imagined…

  • Fight terrifying monsters that lurk in the dark corners of Busan, mutated by the fallout of the impact.

  • Uncover the truth of what really hit Busan that day. What are these strange growths unravelling from the meteor impact, and why has it corrupted what little life remains in the aftermath?

  • Explore a beautiful city in ruins, from shoreline towns and temples to the urban center.

  • Defend yourself with an array of abilities; shoot, stab, kick and counter as an expert soldier trained in firearm and martial combat.

  • Perfect your fighting skills and get rewarded. Cleaner kills means more Genome Points, which can be traded for powerful gear upgrades.

  • Take on huge, terrifying bosses. Seo-Yeon has no idea just how bad the mutations can get in the heart of the city. Be prepared for anything.
