One of the things I remember when getting into 40k was people complaining about how StarCraft stole the Space Marines from 40k. It didn't take me long to see exactly what they meant but I wasn't going to be butthurt about it. I started playing Space Marines in 40k during 3rd Edition, and most of the old fluff had already been retconned. Ah geek memories.
See the teaser page here.
I hope they bring back Tarpit D maps.
And I'm done waxing nostalgic this morning.
