HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Basically, let's turn a Zaporozhets into a Mercedes:D
Initially, the mod was created to improve the game's controls, not to change the gameplay itself – that's why there's no need to bring in everything seen in other games. Or, if you can't resist, do it yourself and don't spoil the classic.
Regarding the backpack with two compartments – it's a reasonable idea, and it might be the option that replaces the three initially proposed button variants.:smile19:
