Walkthroughs for custom maps.

The name "Bug-Race" probably hints at exploiting game bugs.

Exactly. Besides the berserker bug, it uses the sacrifice bug, the firewall bug, the admiral's hat bug, the earthquake bug, and the infinite ballista shot bug. Despite having figured out dozens of the author's tricks, I still got stuck somewhere halfway through. I'll think about it a bit more myself, but I feel like I'll have to write to Nautilus to get some hints. For example, one of the battles that's stopping me: we only have 10 upgraded snakes and 10 red dragons, there's an angel alliance, we can drop part of the army in a neighboring garrison, we need to attack a hero defending a castle (fort without ranged towers), who has 3 stacks: 1000 azure dragons, 1000 gold dragons, 1000 ancient creatures. We can't lose anyone, there's no force field, resurrection, or berserker, but almost all other magic is available.
