Demolition charge
OpenFeint’s Free Game of the Day app and website are looking to provide another portal for free games.
They're beneficial to developers due to the additional downloads, and to players because, well, it’s free isn’t it?.
For today only (though, we’re yet to see anyone rigidly stick to such a short period of gratuity), Silver award winning Sentinel 2: Earth Defense from UK developer Origin 8 is free for all.
Yes, it’s one of the innumerable tower defence titles on iPhone, but it’s a great one.
