Cheat Codes for Tribes of the East.

Of course, there are, and I made them myself – other sites don't have instructions on how to create the codes.
bind show_console '`' – insert this into input_a2.cfg (but first, you need to open it with Notepad). The file itself is located in the Heroes of Might and Magic V - Tribes of the East folder, in the profiles, default_profile folder.

// obsolete, but strictly need for compatibility with some interfaces
bind close_window 'ESC'
bind confirm_action 'ENTER'
bind confirm_action 'NUM_ENTER'
bind show_console '`'

//===========================================================================
// Interface-specific sections

If so, save it.

In autoexec_a2.cfg, which is located in the profiles folder, add the following to the end: setvar dev_console_password = schwinge-des-todes

The end should look like this:
//============================================================================
// Startup
exec profiles\map-aliases.cfg
exec profiles\start.cfg
setvar dev_console_password = schwinge-des-todes

If so, save it.

And finally, add bind show_console '`' to the input_a2.cfg file, which is located in "C:/Documents and Settings/Owner/My Documents/My Games/Heroes of Might and Magic V — Tribes of the East/Profiles/Owner" (Owner is the account name).

In the file, this section should look like this:

// obsolete, but strictly need for compatibility with some interfaces
bind close_window 'ESC'
bind confirm_action 'ENTER'
bind confirm_action 'NUM_ENTER'
bind show_console '`'

//===========================================================================
// Interface-specific sections

Save it if it's correct, start the game, load a save, and check. If you followed my somewhat confusing instructions, pressing the key will open the console, where you need to enter the codes. But before that, to make the codes work in the console, you need to type enable_cheats. A message will appear saying that the codes now work, and then enter the code you need. You need to type enable_cheats on each mission, once.
