This run was done using KeeperFX Version 0.4.6 (Unofficial Build), using the Levels taken from the GOG version of the game. I switched to using this version as it is the recommended version for Speed runs.

Couple improvements that allowed me to shave off 1 second. First was better fights, this level is very luck based as your minions and the heroes can hit or miss attacks, ideally you want to land all your hits while the heroes misses all of theirs (many dead runs because of bad fights).

Secondly is the use of 6-7 beetles. after the first wave, you can still get monster spawns (up to a maximum of 7 for this level). so once you get the 5 beetles for the first 2 tunnelers, you can get 1 additional beetle spawn for a total of 6 for the knight fight, possibly ending the fight faster as demonstrated in this run, allowing me to get lucky with a 3:02.

Strategy used is same as Zoonel's with my own improvements.
