Activision has announced the "Call of Duty: Infinite Warfare" free trial full game, but it will only last for five days.

According to Polygon, this could be in response to the report that the game is not selling as the studio expected.

The "Call of Duty: Infinite Warfare" free trial full game starts Thursday, Dec. 15, and will end on Tuesday, Dec. 20. It will be available for download on PC, Xbox One and PlayStation 4. Users get to play chapters one and two of the campaign, multiplayer mode but the level cap is limited to 15, alongside the zombies mode but with a level cap of 3.

Activision bad needs to prop up the sales of the game through marketing promos like these. According to CNBC, the sales of the title are as bad as the reviews, and that's saying a lot.

For instance, the physical game sales in the US dropped to almost 50% last month against the data for the same period last year on "Call of Duty: Black Ops III. Reportedly, the number of units sold is 17% below the target.

And the sales for "Infinite Warfare" also translated to year-on-year data in the UK as well so clearly Activision has a problem on its hands. Activision Blizzard shares is also down 20% last month against figures in October.

Those who play the "Call of Duty: Infinite Warfare" free trial full game, and they decide to purchase the game, all their achievements, progress and goodies will carry over to the full edition.
