Mind = blown. Not even a week after Steam’s EA week finishes, Valve announce, starting today, a massive summer sale going on until the 4th July with sales on pretty much everything in the Steam Store. There are developer packs ranging from 25% off to 75% off, two indie packages of 5 games each, and separate sales on a bunch of great games.

From the looks of it, there will be daily deals throughout the duration of the sale, so it’s going to pay to keep and eye on the Steam Store page for the best ones. These are the best deals I can see currently available.

You’re too late for this one, it wasn’t a great deal £10 each for Crysis and Warhead.

Bad Company 2 for £20 is well worth it if you haven’t got it already. Pre-order Medal Of Honor and get access to the beta. If you already have BC2, then you get to play on the 17th (4 days earlier).

C&C4 is meant to be a poor end to the series, though some previous games may be on offer if you’re interested. Red Alert 3 isn’t a bad game.

Need For Speed Shift and Burnout Paradise are both great games. NFS:S is the first game to take the series in a realistic, track racing direction. If you like racing games, these could be well worth £10.

Mirror’s Edge is a great freestyle running game, shame the combat is so awful and unnecessary. Dead Space is a must if you like your scary games. I expect both of these to be less than £5.

Mass Effect will most probably be less than £5, while the sequel will be 50% off at £15. Both well worth picking up. Play the first one before the sequel if you can.

The pick of the crop, Dragon Age is the best RPG in decades. If you don’t have this, pick it up for most likely £15. Awakenings, the expansion to Dragon Age, is also worth picking up for £10, it provides an additional 15 excellent hours of gameplay.
