Amazon continues its streak of solid deals on downloadable PC games. This time in their "Farewell to February" sale they have a handful of co-op titles for some low prices included the recently released Darkness II and last years hilariously awesome open world game, Saints Row the Third. Both of those games are only $25.
I also spy Dawn of War II: Gold Editon for $10, Warhammer 40k: Space Marine for $15, and Trine for the ridiculously low price of $1.24.
The full list of available titles on sale are available right here.
