When the The Division beta launches next week on January 28th on Xbox One, and January 29th on PlayStation 4 and PC, it'll have a pretty hefty download size. Reddit user legate213 reports that the install file is over 26GB on PC.
But worry not, because according to Ubisoft's French Facebook page you can pre-load the beta 48 hours before it actually launches.
That means, that everyone who is lucky enough to gain access, should be able to play a fair chunk until the beta ends on January 31st on all platforms.
