If you didnt already know about Xbox Lives upcoming Block Party event then allow me to elaborate on what is is about and some extra things that have been announced too.
Xbox Live Block Party is an event during March which see's the release of 4 Xbox Live Arcade titles - Scrap Metal, Perfect Dark, Toy Soldiers and Game Room. Purchasing all of these Arcade games scores you an extra 400MSP in return - how nice of Microsoft.
However X360A have discovered that there is also going to be a bunch of new Avatar gear starting from March 3rd, these items range from cola dispensing hats, plaid shorts, plastic jelly shoes and a BBQ grill.
Also from 1700GMT on March 26th until 1700GMT March 29th there will also be a free Xbox Live House/Block Party Multiplayer Unlock Weekend for Silver members - so if your silver then get your game on!
