Well someone had to make a Meet the Medic heart. This is actually my first Source model, so let me know of ANY bugs that should arise, immediately. The zip comes with 3 files. One has a single non-übered texture, another includes a team-colored über textured heart, and the last has two models of the heart that doesn't replace anything. The models are of a normal size heart, and a... "Mega Baboon" sized one. Feel free to use the models, but please give credit.
Also before anyone goes and asks... NO, there are no jigglebones for two reasons. One, I'm using the brand new version of Blender, so I'm still getting use to all the new controls. And two, it's really unnecessary since the model is really small.
