Longbow Digital Arts' Seumas McNally sends word of some new screenshots of Tread Marks on the Tread Marks website showing off the new Plasma Gun effects in this upcoming tank racing/combat game. There is also word there that the follow-up Tread Marks test is taking longer than expected, but when available, will offer "full Internet multi-player support, with Master Servers to list the currently running game servers, and a chat interface similar to IRC where you'll be able to get together with other players before and after the games."
