Hedgewars 0.9.22 has been released!

Get it from the Download page.

This release features a new weapon or map object, the air mine.

This is a floating proximity bomb which will float around and follows hedgehogs who are careless to stand nearby it. Once close enough, the air mine timer starts, after which the air mine will explode. The explosion is weaker than of regular mines, but this is enough to lose a turn and annoy your enemy to death.

The air mine can appear as land object (like regular mines) or be fired.

New features:

• New Weapon / Map object: air mine
• Various tweaks to the interface and in-game chat (See here)
• Extensive changes to TechRacer: Variable terrain types, enhanced parameters, hwmap interpreter, fuel limiter, etc.
• Added 6 TechRacer maps
• Added 3 Speed Shoppa challenges (missions in which you must collect all crates as fast as possible): Shoppa Love, Ropes and Crates, The Customer is King
• Added 24 new flags, replaced 1 existing flag
• Improved “Art” theme (See here)
• Map complexity in the “Tunnels” style can be adjusted by using the map slider
• Maze size in the “DiagonalMaze” style can be adjusted by using the map slider
• Added default Sudden Death background music
• New script (primarily for developers): HedgeEditor

Gameplay tweaks:

• Hammer now does more damage (50% instead of 1 third) when the Extra Damage utility is used
• Hammer damage is now rounded up. This means it can be used to execute hedgehogs with only 1 HP
• Melon bomb pieces, air strike bombs and a couple of other things now bounce on rubber

Bugfixes / minor weaks:

• Fixed the bad rubber shape
• TechRacer maps now have proper previews (and they show checkpoints, too)
• Game modifier “Divided teams” will now just be ignored when using more or less than 2 teams or clans, instead of displaying a fatal error
• Fixed: Wind indicator being wrong in certain situations
• Reduced main menu music volume
• The game will now fall back to the default voicepack if a team's voicepack is not locally installed (instead of rendering the team voiceless)
• Generated bridges/girders are now connected better to the land mass
• Many other bug fixes
