I love this game. It feels retro. Also a bit harder than doom. I play this game on my RG351V and DSi.
Godfather of all shooter games. And now available in Linux. Plays super smooth. It rocks just the same as it did before. Still spooky and terrifying because of the simplicity of the hardcore action. Massive amount of possibilities to change all sorts of settings. But straight out of the box it plays simply great! So happy that Doom is back in my life with Linux !
Doom is great, freedoom is equally great. Some monsters are better and some not (the flame thrower and the plasma spiders aren't well made) , but the levels of phase II is far better than classic Doom II. A must have.
Very nice free port of the Doom wad files, very similar graphics, nice annoying enemies, good fun to play. You'll need a Doom engine to play this game, I suggest prboom+. Highly recommended.
Freedoom is an attempt to make an opensource set of doom art/levels. Unfortunately many of the levels are not well done. However with PrBoom and freedoom you can get many old doom mods to work reasonably well. Though a few of the 3rd party levels with fancy scripts can become impossible to complete normally.
At times, it's a bit too derivative, though I suppose that's the point. Nevertheless, it's nice that it's available.
