If you somehow haven't played the fast-paced first-person masterpiece that is the 2016 Doom reboot, now is a pretty great time to give it a shot. The game was already discounted to $6 for the Steam Winter Sale, but now it's 50 cents cheaper from Newegg.
Newegg delivers the game as a Steam product key, so it's functionally identical to buying the title from Steam, execept you save $0.50 in the process. That's a whole 50 cents you could put towards other games! Think of the possibilities.
Just like the regular Steam version, all DLC is included: Unto the Evil, Hell Followed, and Bloodfall. That should be enough to hold you over until Doom Eternal comes out in a few months.
DOOM 2016 + All DLC | $5.49 ($14.50 off)
The 2016 reboot of Doom, plus all its DLC, is just $5.49 from Newegg. That's $0.50 cheaper than the current Steam price, and the game is activated through Steam anyways.
