Chillingo experiments with freemium games, re-releases Monster Mayhem
It's all the rage

Publisher Chillingo has dabbled in freemium iOS games before, but it's generally prefered to stick to its favourite 99c price standard.
Perhaps the re-booting of Monster Mayhem, previously released for 99c in May 2010, but now also available free with in-app purchases, suggests a new direction.
New ways to payThe game, a castle defence game that gained a Pocket Gamer Bronze award, has been reworked with in-game currency Coins, available from 99c, €0.79 or 69p for 10,000 or $5.99, €4.99 or £3.99 for a million coins. You use the coins to buy weapons include a flamethrower, machine gun and atomic bomb.
You can also now unlock all stages of the game for $2.99, €2.39 or £1.99.
Significantly, the full game remains available for iPhone at its standard price with IAP, while the freemium version is available here [iTunes links].
