Spore Patch 3 is now available through the in-game update menu, or at the official Spore site. Only three fixes this time around:

• Fix for esc key not bringing up Options in Galaxy Game Entry
• Fix for creator backgrounds appearing on small sporepedia cards
• Update to help keep achievements on the server in sync with achievements in the game

But, as announced earlier, this small fixes come with extra goodies, for Maxis have included no less than 24 exoskeleton limbs (shown below)

Get cracking on your new insect creations and show them off in the Simphoni forums!
