GameMaker Studio version 1.2.1214 was just released, and with it comes an offer to upgrade to the Standard edition free of charge. Valued at $50, GameMaker Studio Standard is a significant improvement upon the free version of the software which imposes harsh restrictions on the resources that developers can make use of.
Additionally, developers can use their free Standard edition license to upgrade to the Professional edition for only $50 more. It’s likely that this is a time-limited offer, so if you’re using the free version of GameMaker Studio be sure to act quickly.
You will need to register for a license key to be sent to you via email, and then you can use that key to upgrade your free version of GameMaker Studio to the Standard edition. Some users are reporting that it has taken up to 60 minutes to receive the email which includes the license key due to current high demand.
This offer is not being extended to users who have GameMaker for Steam.
Also for a limited time, YoYo Games is offering GameMaker: Studio Master Collection — including Professional, the YoYo Compiler and all current and future export modules — for $499.99, $300 off the regular price! This offer is valid from November 26 through December 3.
