One of my favourite missions so far completely cements the satirical nature of the game, as you undertake a task for Lester in order to then secure him as your point-man on heist missions. The task is to sneak into the Lifeinvader offices (a social networking site clearly modeled on Facebook) and sabotage a prototype phone, but firstly, you have to kit yourself out with a hipster outfit from the Suburban store. Once you gain access, you help out a programmer in the office by getting rid of a virus (along with a series of porn pop-ups) on his system, and finally, you plant a device on the prototype phone. It's worth hanging around in the offices for a little while though, because Rockstar have clearly had fun mocking the laid-back culture of new-age corporatism; listen to the riotous dialogue, and marvel at the fact that the office is even kitted out with its own sweat lodge! Once you leave the offices, you head home and switch on the TV, to see Lifeinvader's Mark Zuckerberg-inspired founder showing off the latest tech. You give him a call, and then BOOM - his head gets blown off in an instant. Shocking, clever and utterly uproarious, this is everything a classic GTA mission needs to be.
