Dying Light players will be able to participate in "something unusual" which Techland says will "radically change the game experience" for one day only tomorrow, April 1.
According to the developer, players will need to use "extreme caution" when handling Antizin injections as the latest batch has been sullied with a foreign contaminant.
The chemical is reportedly non-toxic, but it will cause odd side-effects for up to 24 hours. Players are also being encouraged by the developer to record said side-effects and upload the video to YouTube using the BadBatch hashtag.
“All undelivered Antizin crates have been destroyed, and we would like to assure the survivors that untainted drops will resume as of April 2," reads the official release announcement. "We urge all the survivors to use extreme care when exhibiting symptoms of the contaminated Antizin injections.”
A public service announcement video has been posted below.
