In response to a so-so reception, developers Tallboys and tinyBuild have announced that their multiplayer first-person shooter, Pandemic Express – Zombie Escape, which first launched in September 2019, has gone free-to-play.

The game will have optional microtransactions to buy in-game currency, though you can earn it through normal play. Under the new system, players will earn stars (the game’s currency) by playing matches that can be spent on costumes, emojis, and in-game music. Anyone who bought the game prior to the free-to-play transition will be given 2000 stars and access to all music tracks as thanks.

For those unfamiliar with Pandemic Express, the game has a group of 30 people attempting to escape a zombie apocalypse, with the twist being that one of them is already infected, granting them certain. The infected player must now munch on the brains of the other 29 people as they run to catch the last train out, as well as fight off the zombie hordes that have amassed against them.
