Original Doom, the classic version, for Android
The application is really nothing more than an engine along with the shareware version of the game. That is, by default you will only be able to play the first episode of Doom. However, in order to access all of the content from Doom 1 and Doom 2 you just have to import the pertinent files from your computer to your device.
Technically speaking, this version of the game for Android devices works very well, with controls that were perfectly adapted to touchscreens and graphics that are identical to those of the original, which didn't need to be updated at all. In addition, you can use the volume buttons on your phone to switch between weapons, making it more comfortable to do so while playing.
Original Doom is an excellent way to enjoy a truly great game. It is one of those immortal games, and now you can easily play it wherever you are, using your mobile phone.
