We've occasionally seen pre-orders for BioShock Infinite break the £18 barrier, but Green Man Gaming are running an intriguing selection of bundles until 17:00 today. £23.99 will net you a pre-order, the original BioShock and the choice of Civilization V, Spec Ops: The Line, BioShock 2 or The Darkness 2.

It's a reasonable saving if you don't own the original BioShock, and as we recently discussed, pre-orders are only worth doing if you can beat the RRP. Shame you can't use the voucher code, but hey, this could be a nifty way of grabbing Spec Ops if you haven't tried it yet. UPDATE: Thanks and credit to Meowingtons at HotUKDeals, who beat us to this by 48 hours.
