Monday 5th – Virtua Tennis 360 signed by Andy Murray, VT sweat top and bag

If you’re lucky enough to win on Monday you’ll be the envy of everyone at your local tennis club with a Virtua Tennis sports bag, jacket and a signed copy of the Virtua Tennis game on the Xbox360. This isn’t signed by anyone, it’s been signed in silver pen (my silver pen I hasten to add) by Britain’s Andy Murray.

Tuesday 6th – Empire: Total War signed artwork

On Tuesday we’re giving you the chance to adorn your wall with some brilliant concept art from the forthcoming Warpath campaign expansion for Empire: Total War. This artwork has been signed, not by Britain’s Andy Murray, but by the chaps over at The Creative Assembly, the game’s developers.

Wednesday 7th – MADWORLD signed artwork, game and t-shirt

We’ve got some more developer-signed artwork for you on Wednesday with our MADWORLD giveaway. On top of the artwork, which shows no sign of an Andy Murray signature, we’re giving away a copy of MADWORLD and a t-shirt.

Thursday 8th – A 12 month subscription to GamesMaster magazine

Thanks to our chums over at Future Publishing, we’re giving you the chance to grab a 12 month subscription to GamesMaster magazine. GamesMaster is the world’s most exciting multi-format games magazine, and is the only magazine to offer comprehensive coverage of the biggest and best games on every machine, every month.

Friday 9th – Empire branded PC from Invasion-Labs

If your current gaming rig is running slower than the 6:00pm out of Waterloo via Guildford, then make sure you enter the competition on Thursday as we’re giving you the chance to win a top-spec’d custom-built Empire: Total War branded PC from Invasion-Labs. This high spec machine boasts a 1GB ATI HD 4870 graphics card, 850w PSU, and an Intel Core i7 920 processor. Hell, we’ll even throw in a copy of the Empire: Total War game. Don’t say we never give you anything.

Saturday 10th – 5 codes to download Sonic and Knuckles off Xbox Live

We’re mixing things up a bit on Saturday as we’re giving five of you the chance to win something. We’ve got five XBLA codes for the classic Mega Drive game Sonic & Knuckles to give away; so make sure you re-tweet and vote if you want to win one of these codes.

Sunday 11th – Sony PlayStation 3 console, SEGA Mega Drive Collection game and rare blue vinyl SEGA music compilation

Sunday’s winner will take home a rather neat little prize; a copy of the SEGA Mega Drive collection on the PlayStation 3, and one of the rare promotional vinyl records (remember those) for the game. The record contains some classic SEGA game tunes.

And that’s not all, as you’ll also get a Sony PlayStation 3 console. This is an 80GB model and comes with a DualShock 3 controller.
