On the old forum I kept track of the fastest speedrun times for each map over the last year of Battleforge (from April 2013 to the end). I will continue this list including the new records from Skylords Reborn starting from January 2019.
All matches were played on the highest difficulty (Expert/ 10 for Battleground).
The Battleground maps are different each month.
All-time speedrun rankings:
1-Player Maps:
Battleground: 12:41.8 Treim May 2020
Behind Enemy Lines: 10:24.4 Prits
