Portal's lesser cousin
Twin Sector is a little-known puzzle adventure that plays out a lot like the classic Portal but if you have played that, then this is going to seem pretty tame and uninvolving in comparison. Even if you haven't experienced Portal though, this is still likely to be little more than a passing diversion on your way to something better. The background to the game describes how humanity has been forced into cryosleep deep beneath the surface, as the land up above has now become uninhabitable. You play the role of a maintenance engineer, woken up by an AI to help fix some of the systems which are now breaking down. As you progress through the game, you'll find there's a bit more mystery going on and which does help to maintain your interest. The gameplay is very much like the aforementioned Portal, being a puzzle adventure which is now viewed from a first-person perspective. Armed with gravity gloves, you'll explore a series of vast environments while manipulating various objects to help you solve numerous puzzles which bar your progress and to take on the hostiles that are also roaming around. Twin Sector is an intriguing little game that could have made for a nice alternative to Portal. It's not terrible by any stretch of the imagination, it's just that it's terribly, terribly bland with little to keep you hooked. The puzzles are all standard stuff, lacking in imagination or challenge, although the story does at least pack in a few surprises. The visuals are decent but overall, this is very middle-of-the-road stuff.
