Really well made game.
There are like no bugs to speak of.
Story, plot, mission progression, reward point system, perfect mood music, hexagon battlefield system, alert mode - all combine to make this a classic.
Made some videos about the game. Mine are nice and easy, compared about what's available on YouTube. Here's one showing how to efficiently speed-run Kill Top, and farm SAS dollars: https://www.youtube.com/watch?v=Q2a6pDBTxvE
Hard mode, using just goblins and centaurs.
Will gladly answer any questions, or help out with this fine old gem of a game. :) Link to forum thread:
