Halo Demo. Tomorrow. on IGN is the report that tomorrow they will be debuting downloads of the playable demo for Halo, Gearbox Software's PC version of Bungie's first-person shooter. Word on the 131 MB demo, which is expected to go online at 1:00 p.m. EDT, is it "will feature 'The Silent Cartographer' from the single-player campaign, 'Blood Gulch' with limited vehicles for your multiplayer satisfaction, as well as support for up to 16 players in Slayer and CTF multiplayer modes." Thanks Frans.
