The incentives, which were announced earlier today as part of the 2012 Budget, will promote "further investment" for developers and jobs.
The publisher first backed trade organisation TIGA and the steps towards tax relief in 2010.
"This is a great first step and should put the UK in a stronger position to compete with other countries offering incentives for videogames production," read a statement issued to Digital Spy.
"The UK is an important centre for development talent, employing 9,000 people in the videogames sector, and anything that promotes further investment should be welcomed."
TIGA succeeded in convincing Labour to introduce a tax credit in March 2010 before it was scrapped by the coalition government in the emergency Budget.
Activision Blizzard publish and produce a number of best-selling franchises including Call of Duty, Skylanders, World of Warcraft and Diablo.
