Gathering evidence from videos, screenshots, attires and special bonuses, we now know several of the matches and arenas that will be featured in WWE 2K16's 2K Showcase mode for Stone Cold Steve Austin.
A user on the WWE 2K forums posted a full list:
- vs. Pillman - Clash Of The Champions XXV
- vs. Steamboat - Bash At The Beach '94
- vs. Whipwreck - November To Remember '95
- vs. Vega - WrestleMania XII or In Your House: Beware Of Dog
- vs. Roberts - King Of The Ring '96
- vs. Hart - Survivor Series '96 (Bret's attire)
- vs. Vader vs. Hart vs. Undertaker - In Your House: Final Four (likely reason for Vader's inclusion, could be for RR '97 though)
- vs. Hart - WrestleMania 13 (likely reason for Shamrock's inclusion)
- vs. Rock - D-Generation X: In Your House (likely reason for NOD's inclusion)
- vs. Michaels - WrestleMania XIV (reason for HHH's retro DX attire in "Oh Hell Yeah" trailer)
- vs. Undertaker - Rock Bottom '98
- vs. McMahon - St. Valentine's Day Massacre '99
- vs. Rock - Backlash '99
- vs. Undertaker - Fully Loaded '99 (X-Pac's attire in IGN screen)
- Royal Rumble 2001
- vs. Triple H - No Way Out 2001
- vs. Rock - WrestleMania X-SEVEN
As you can see, there are several matches that are in WWE 2K16 that weren't featured in WWE '13. Although Stone Cold's match with The Rock at WrestleMania X-Seven could be seen as a duplicate as that match already featured in WWE 2K14.
There are only 17 matches known so far. We are likely to know all of the matches soon enough. It's only one more month until WWE 2K16 comes out on October 27th!
