In following Ethan Nicolas’ decision to release a free ‘lite’ version of his iShoot tank game (which coincided with the full paid version skyrocketing to #1 at the App Store), developers all over have now adopted this strategy, giving users the chance to ‘try before they buy’. This past week, we saw some big name titles go lite on us; Time Crisis Strike, Payback, Sentinel and even a Top 10 contender in Zombieville USA. Artificial Life (Amateur Surgeon and Shooter), has released the very neat BMW Z4 app that allows you to paint a canvas while test driving the bimmer. Sweet. Check out the list below for some worthwhile apps to try out free.
