The first look at where GTA V's much-maligned heist missions were going to come from, IV's Heat-style take on stealing bags of cash from a bank in the middle of the city easily became the highlight of the entire game - not to mention one of the most frustrating missions overall if you couldn't nail the escape. However, say you managed to get everything right first time through, it was a brilliant mesh-together of GTA IV's new combat, graphics that were pretty amazing at the time and one final tunnel-crawl that seemed to go on forever before you'd lose your wanted level. IV might be remembered as the title that feels the least like GTA across the board, but this was one of a handful of moments where Rockstar set up a great mission and just said "Have fun!"
