Made this instead of working on my own game. I wanted to make the Egg-Mobile more 'unique' to say the least by taking elements from the OVA, Movie, and even Sonic X's Egg-Mobile. However, there's also a version that has a more traditional-looking Egg-Mobile if you fancy that. (The Eggpack sprite is certainly 100% not inspired by the SRB2 mod of the same name totally)
What's included? A 'default' Egg-Mobile. It's golden and red and comes equipped with missile launchers. A 'traditional' Egg-Mobile. It's your standard silver and black Egg-Mobile. Comes equipped with wings and a jet for further mobility. An Eggpack fleeing sprite. Eggman flies away with his Eggpack after being defeated. Various faces for different actions. Just replace the default face with these in the Egg-mobile sprite and you're good to go.
