Have you been tempted to give NGUI a try, but just don't want to commit to spending money on something that you may not use? Well, you're in luck. You can now download the full version of NGUI for free.
Click the logo to download the Unity Package.
What's in the package? The last version of NGUI 2 cycle -- NGUI 2.7.0.
What's the catch? NGUI 2 has been deprecated in September 2013 when NGUI 3 came out, so it's an older version that won't have all the latest features and optimizations of the current one. It also doesn't come with support. The last restriction is that if used for commercial purposes, it falls under the same restrictions as Unity Free: "free version may not be licensed by a commercial entity with annual gross revenues (based on fiscal year) in excess of US$100,000, or by an educational, non-profit or government entity with an annual budget of over US$100,000"
But hey, it's free!
