Seeing that picture could have put all kinds of ideas in your head, which is why I didn't make the headline cruelly vague. What it all actually denotes is Gordon Freeman’s rather surprising presence in the Steam version of Renegade Ops, Avalanche's top-down, four player vehicle-based destructathon. Gordon will be driving his buggy and he’s bringing some antlions along to use in a special attack. Oh, Gordon, you’re so science. Avalanche did promise some extras for the Steam version of the game after delivering it to console-dwellers before we PC folk and it’s good of them to follow through on that promise. They’ve even given us a Gordon-specific trailer along with a release date: October 14th.
I’m presuming there will shortly be confirmation that Renegade Ops takes place in the Half Life universe.
