I know many people are unhappy with AH2 delay. Yesterday my friend 584752 visited HTC headquarter to talk with HT and Pyro, and he has some very good news about the AH2. All those last minute changes explain why release is postponed:
1) PK killer switch added to the game. You probably know that new players are very unhappy when killed by guys who are at the next levels, so now they can switch Person Killer off, and that is it! They can't kill, and can't be killed.
2) Instead of upgrades of plane you can get with better rank in TOD, new interesting twists added to keep people interested in getting ranks. Now, several special items added to game, for example: "Upgraded Hispano +7" "The shining armor +3". Also some items can be found.
3) Several bonuses added, HT said that it will be big pink donats all other the skies which you can fly thru, and this will restore your health.
They also promised they will release AH2 in Q4 of some year.
