As Christmas is less than 24 hours away as we write this, we have been getting various e-cards from developers and publishers celebrating the holiday season. You can see one of them above as Blizzard combines their Warcraft and StarCraft universes for an interesting Santa interpretation. You can see some other e-card we have gotten in our email boxes from developers like Croteam, Hi-Rez Studios, NCsoft and others.

But that's not all. Croteam has also released a trailer showing off some Santas in some "serious" co-op action which you can check out after the jump. Also Relic and THQ have released their own video Christmas card which we are betting is also a big hint about what we might get in Relic's next game Warhammer 40,000 Dawn of War II Chaos Rising.
