Boy, Ken Levine sure knows how to build a world. Having already created the incredible, underwater utopia of Rapture (before annihilating it from the inside), Levine went even bigger with Infinite's world. Columbia is a city with a difference; it floats in the sky. The platforms constantly shift and move to give the area a freeform feel and the blue skies cluttered with wispy clouds make it oh-so picturesque. The beginning of the game exemplifies this perfectly; your first steps hook you into the world and as the story starts to develop, you discover the dark issues lurking beneath the watercolour landscape. Additionally, Infinite's pace is much brisker than the original Bioshock's; there's less back-tracking and, due to events within the city, you're constantly travelling at speed. With the exception of one section (the infamous Lady Comstock boss fight), everything in Infinite feels fresh and exciting, making your playthrough an absolute blast. Sadly, one playthrough is all most people will manage. With the story wrapped up in the excellent final scenes, there's little motivation to go and replay the game immediately. The newly unlocked 1999 Mode might appeal to the completionist but even then, the less than inspiring gameplay might put even the most dedicated of achievement hunters off. Infinite is a truly great game but sadly, the appeal wears off massively after one playthrough.
