Limbs are type of creature parts that can be attached to the creature's body, each with its own unique look.
Once a limb has been placed, joints can be arranged and moved by clicking them. Once placed, each joint and limb segment can be individually sculpted with the mouse wheel.
Holding the Ctrl key allows to cut and reattach segments of limbs to other limbs, making it possible to create complex limbs unavailable otherwise. Multiple limbs can be attached to a single joint creating a split, but limbs cannot merge back (for example a limb can be arranged to form a Y shape, but it is not possible to create loops of limbs). Multiple hands and feet can then be attached to limbs that branch.
There also exists an exploit to make limbs invisible, see Invisible Limbs for more info.
There are 24 core limbs, 24 exoskeleton limbs, and 4 mech limbs. They all come with either hands or feet, and with the exception of the robot parts, hands provide Graspers and feet have Speed 1. The hands and feet of core and exoskeleton parts are not available from the hands/feet tabs and cost 20.
The price of each limb is calculated from the price of its hand or feet plus the price of each segment. All the segments cost 15 and can be sold independently of the rest of the limb. Each limb segment also has a complexity of 1.5.
Only the first column is available in the free creature creator demo.
Exoskeleton limbs were introduced in Patch 1.03.
Bot limbs are only available with the Spore Bot Parts Pack.
