For those eager to try out the demo for the latest Sonic game, you will not have to wait much longer. The EU Playstation blog has confirmed that the Sonic Generations demo will be online from tomorrow, which just so happens to be the birthday of Sonic the Hedgehog, so for those all eager to try out the physics and control in the latest Sonic title, the wait is almost over.
But it does not stop there, for a duration of 20 days only, PSN members can purchase the 20th Anniversery Bundle from the 23rd of June which will include the following; Sonic the Hedgehog 1 and 2, Sonic the Hedgehog 4: Episode 1 (Along with dynamic theme) and Sonic Adventure DX (With DX add-on) all for £13.99/€17.99, a decent price for a good amount of games.
