Doom has been ported to Series 60 and Series 80 handsets
"Whilst this isn't the first time that a Doom port has graced Symbian based handsets the list of features in C2Doom, written by Markus Mertama, is impressive with support for several versions of Doom and Doom 2, full audio, user definable controls, and up to 4 players over bluetooth. It all runs incredibly well, too, both Doom and Doom 2 are playable with silky smooth graphics on the Nokia 6630 Midlet-Review tested them on, athough we wern't able to test the bluetooth multiplayer functions at the time of going to press.
