Day two of Valve‘s Autumn sale 2011 is under way, and with it a whole new bunch of super cheap games have been announced. Steam sales aren’t quite what they were about a year ago thanks to the Rand’s recent plummet, but there is still some great value to be found.

Yesterday the likes of Mass Effect 2 and Portal 2 were on the frontlines, not to mention Risen and indie darlings Orcs Must Die! and the Dejobaan collection going for super cheap.

While today’s lineup is lacking any really big hitters, it makes up with it with the likes of the Total War Megapack, Operation Flashpoint: Red River, and the Monkey Island Special Edition bundle.

Then there is Fallout: New Vegas which is going for a cheap lunch, along with Zeno Clash and Roller Coaster Tycoon 3, all of which are worth checking out if you don’t already own them.

For today only you can get the following:

Zeno Clash $14.99 $3.74 (R32)

Sniper: Ghost Warrior $29.99 $5.99 (R51)

Two Worlds franchise sale

LA Noire $49.99 $29.99 (R255)
