The food limit has beed set to 300 and the trees have 99999 hit points so you shouldn't have problems with lumber.
2 new races have been added instead of the Human and Orc races. These new races are Void and Blessed Army.
The Void race is completed but the Blessed Army is only a beta race so don't tell me it's to empty.
The 2 remaining races (Undead, Night Elves) are nearly untouched. The only modifications are that the primary buildings produce with 5 more additional food and the shops sell a tiny primary building (trust me, if you want to build a base in that cidatel you'll need it).
About the citadel in the middle, you could try to attack it on your own, but an ally would be a great help. You can get into it using the 4 portals outside the walls. All of them transport you in the same place (in the northren part of the citadel). To exit the citadel, you'll need to fight your way through all the monsters until you reach in the southern part of the citadel. There, you will find a portal that leads you in the south of the citadel.
In it's center there are 2 bosses:
- Akama - He is rather stronger than the normal one but once you kill him a rune will drop from him and picking that rune will revive him as a Hero on your side.
- Eradar Warlock - Killing him will be a real challenge because he can kill a Hero with 3 attacks. No way you could kill him at your first attempt. The good part is that he doesn't regenerate hit points so his time WILL come. The items dropped from him will make your Hero the strongest unit in the map so think well before deciding to give up.
