Halo developer Bungie has announced plans to raise money for the relief effort in Haiti following last week's catastrophic earthquake.
The studio has said that it will divert 100 per cent of profits on merchandise sold through its online store to the American Red Cross.
Gamers have also been invited to play Halo 3 or Halo 3: ODST online this Wednesday and Thursday while wearing a special emblem to signify their support. For every 1000 gamers who do, Bungie will donate $100, up to a maximum of $77,000.
The studio has also encouraged gamers to simply donate, even if they don't fancy taking part in the Bungie-related activities, referring them to charitynavigator.org for advice.
On Saturday, fellow US developer PopCap donated all proceeds from game sales to Partners in Health, while Zynga has reportedly raised over $1.2 million through campaigns across its social games FarmVille, Mafia Wars and Zynga Poker.
