id Software announces Doom 4

Nearly four years since the release of Doom 3, id Software on Wednesday confirmed development of the fourth game in the series.

Doom 3 (PC, 2004)

The announcement was more of a hiring call for developers than a notice of game details, but it was confirmation nonetheless of the game's looming release.

It's unclear when the shooter will arrive and for which platforms, but being that Doom 3 released on Xbox in 2005, and given the waning sales of PC games, a simultaneous launch of Doom 4 on PC, Xbox 360, and PS3 would not be unlikely.

In any case, "the ultimate battle against evil continues," said the pioneer of first-person shooters, id Software.

i liked doom 3

Doom 3 on the PC/XBox was a good game. Doom 3 included both the original and Doom 2 on the same disk.
BTW: I could not beat the last boss on Doom 3. not even on easy had no idea what to do lol. It was a huge scary thing. I even tried to use invincibility and all weapons and unlimited ammo and still could not beat it.
