Game Modes

r18544 Regicide (start the game with a hero and become defeated if it's killed) (#2160, r18731)
r18075 Make Wonder Victory gamemode playable by allowing the timeout to be varied (#3234, r18189 r18411)

Gameplay & Balancing

  • "New" buildings and champions (that have been hidden in few scenario maps) can now be produced in every match (marked in bold).
  • The aim of the balancing changes is to stop players from destroying buildings with infantry and cavalry, enforce the use of siege engines and reducing the spamming of champions by making them more expensive.
  • Early attacks are more feasible by adding town phase champions, nerfing the damage of garrisoned buildings but also allowing early towers to be upgraded to stone towers.


r18024 Make previously unused buildings and champions available:

Athenians and Sparta can build up to two Royal Stoa and produce Sword- and Skirmisher Infantry Champions there
Britons can build a Crannog, which is both a Civic Center and a Dock
Persians can build up to two halls from which Spear- and Skirmisher Infantry Champions and War Elephants can be produced (r18043, r18901)
Romans can build (at most one) Temple of Vesta, Persians the Ishtar Gate, which increase the capture-strength of garrisoned units within 75m of the temple (r18753)
