If you weren't able to attend, Microsoft and BioWare have published full video of their respective San Diego Comic Con panels on Halo: the Master Chief Collection and the next Mass Effect. If you've got 90 minutes spare, you could do worse than perching right here and checking them out - the Halo video's up top with Mass Effect below the break.
If you've been lost in space for the last month and this is the first you've heard of either of these things, let's fill you in. Halo: The Master Chief Collection is a remastered compilation of Halos 1-4, and it's coming to Xbox One on November 11. It also includes access to the Ridley Scott live-action Halo: Nightfall series, as well as the Halo 5 multiplayer beta, due to begin in December.
