When looking up the different kind of hospitals i also took inspiration from the real hospitals that were used in the 1940s time era to see the layout of the hospital to see what kind of environment they were living in.
When doing research on my 2D game i looked up the types of sci-fi games and movies that there are like EVE which is a space game where the player roams a galaxy or Mass Effect where players take control of a man trying to protect his planet by going to other planets. I also looked up the different kind of top down 2D shooters that there are like galactica and space invaders where players take place as a space ship trying to destroy aliens.
This was the sprite that i made for my 2D shooter game.I created this sprite in Photoshop from another spaceship that looked familiar
As my arena is going to be a hospital i chose to have a prey simple layout. The grey box shows the space whee you will be walking around, The yellow shows where the hospital rooms are placed in my environment, The red shows he hospital bed hat is in he middle of the map, The blue shows the interactables like the ammo crates and health packs and the red shows the propane tank that is at the back of the room.
