My boyfriend introduced me to half life a while ago, and I've been playing through it with him! I really like it so far. I've never been a huge science fiction fan, but I love the story and the vibe of this game. So I drew these sort-of sketch page things for the houndeye and the headcrab. And then I also added the vortigaunt too as like a bonus xD. I don't know why I added the font on them, I guess I was inspired by how some textbooks and field guides have diagrams of different animal species and things??

I might make a part two, because there are many more species from this game I can draw!!

I'm only about halfway through the game right now, so please no spoilers in the comments!!! And if I got anything canonically wrong about the anatomy or anything else, it's also because I haven't finished the game and I don't want to look up too much because again, I don't want spoilers xD But yeah, I really enjoyed doing these!! It started out as a bunch of marker and pen drawings in my sketchbook.
