As we near the close of 2015 and there are a huge amount of spotlight-stealing high-profile games hogging the limelight, it's very easy to focus on the most expensive ones out there, rather than those that are actually worth your time. Over the past five years you've torn through the dusty trail on Red Dead, strolled through the floating utopia-gone-sour of Columbia in Bioshock Infinite and sent a few thousand orc heads flying skywards in Shadow of Mordor - but what of the occasionally spectacular indie scene, the genius ideas that were forced to make ends meet with smaller budgets, or the titles that simply got thrown to the wayside as more popular games barrelled on past? They're all here, they all have something incredible to offer, and best of all at this stage - they're (nearly) all a fraction of the price they were at launch.
21. Singularity
When was the last time you played a first-person shooter that actually had a genuinely unique game mechanic? I'm not talking about the in-air dodges the latest Call of Duty and Halos now have - I mean a fundamental in-game weapon or mechanic that actually changes the way you play, like Red Faction's old-school GeoMod technology, or here, Singularity's time-displacement gun. Think about weaponising Elizabeth from Bioshock Infinite's fancy warping powers; you can fiddle with the environment and revert broken platforms back into working order, hop through all sorts of butterfly effected time periods, obliterate enemies by ageing them out of existence, and plenty more. Thanks to Raven Software's meaty gunplay, the whole thing thunders along at a great pace too - a killer time-related plot twist spinning everything on its head right at the end - but it's the solid premise of remixing history alongside providing one of the best weapons since the Portal gun, that really elevates this above the rest.
