We could use some player types in Blockland that aren't based on animals and are more akin to alien species who walk on two legs. Edits of the default Blockland player-type, perhaps.
If you still don't know what the hell I'm talking about and need an example,
here's a picture. I think these kind of playertypes are important because it makes the aliens truly
alien.
When all the species in an RP look like humans with different skin colors, that really breaks the fantasy atmosphere. The mutalisk was a good start but got no-where. Besides, the mutalisk was purposely designed to be feral. I think these types of playertypes could have implications for a "humans vs aliens" deathmatch thing.
