VCMI 1.6.0 released

A new major release just arrived: VCMI 1.6.0! This time we focused
on AI, visuals and numerous GUI and UX additions for even more
immersive experience.

Better visuals

VCMI now can improve graphics quality thanks to smart xBRZ upscaling,
plus support for high-resolution assets – perfect for high-resolution
displays (and smartphones too).

Smarter AI

Our adventure map AI (Nullkiller AI) was greatly enhanced, and some
combat AI tweaks also landed.

Heroes Chronicles support

If you own Heroes Chronicles on GOG, you can now import these
campaigns seamlessly via the “import files” option in our Launcher.

Statistics and handicap

New handicap feature can not only handle gold transfer known from
PvP games, but also change growth and income to adjust game challenge
over wide range. And once a scenario is finished, a new screen
shows detailed statistics like resource flow and army power over
time.

Spell research and quick spell panel

We’ve added a simplified version of long-requested spell research,
which you can enable through HotA mod. In combat, a new spell
quick-selection panel (with optional hotkeys) makes casting your
favorite spells faster than ever.

Handy shortcuts

Holding Alt on the adventure map now highlights interactive objects.
You can also re-roll spells in your town’s guild (via HotA mod),
sort artifacts artifacts and more.
