Eidos life president and GamesAid trustee Ian Livingstone said: "Once again GamesAid has been overwhelmed by the incredible support we have received from indie games developers. littleBIGbunch only exists thanks to their generosity.
"This year we have a fantastic collection of games which we hope will appeal to gamers everywhere. Choose five great games from our selection and know that half your money is going to GamesAid and half to the amazing developers."
