The upcoming reboot of DOOM went into closed alpha last year, during which enterprising dataminers set about to uncover as much information as possible.
Unsurprisingly, the datamining has revealed the return of some familiar enemies and weapons, but also included some surprises such as the return of the Spider Mastermind.
What is surprising though is that from the datamining, it appears that players will face random boss encounters during the campaign. Posting on Doomworld, user Mr Dope appears to be a source for much of this information and has posted additional information on the forums.
DOOM will be available for PC, PS4 and Xbox One on 13 May.
