Template:Doom alpha versions
Screenshot from Doom 0.5
Doom 0.5 was an alpha version of Doom, released on May 22, 1993 to testers. This version included a number of features in addition to those found in the Doom 0.4 alpha version:
- Collision detection between objects. It is possible to walk into monsters and pick up items.
- It is possible to shoot monsters. There is still no animation at this stage, however; when monsters are shot, they simply vanish.
- A working status bar and the ability to change the screen size.
- A working menu.
- Animated floors and working doors.
- An Automap.
- Skill levels. The easiest is "I just want to kill", rather than the release version's "I'm too young to die".
- The rifles sprite has changed, though the bayonet uses the same sprite.
After the player quits the game, the "farewell" screen states that it is a preview of Doom: Evil Unleashed.
