Age of Doom is basically a Diablo-style isometric shooter. The sound effects and sprites are all drawn from the original Doom games, but there are sound clips included in the campaign from later in the series. The campaign includes four episodes, plus a tutorial mission. Modder Hellknight61 says a final episode, called ‘Hellhole Teleportation Portal Gate’ is still in the works. You can swap weapons and shift tactics using Age of Empires II’s chat panel – it’s kind of genius.
Age of Empires 2 is a game that everyone enjoys. The original Doom is well-liked by all. So why not combine these two fantastic vintage games into one clicky, sticky adventure? That’s at least the premise behind Age of Doom, an Age of Empires 2 mod that incorporates artwork, audio, and other elements from the Doom series to create an entirely new Doom-themed campaign.
You’ll start out in the ruins of an ancient human civilisation discovered on Mars, eventually making your way to a UAC corporation base that’s been invaded, as they inevitably all are, by a horde of demons. After that, you’ll have to travel to the moons of Phobos and Deimos to shut down the hell portals there.
There’s plenty more to read on the ModDB page, as Hellknight61 has created an impressive range of guides and tutorials to help get you started with the mod.
Each mission has objectives (which you can read about on your ‘PDA’), and yes, you do get a shotgun.
