Decent game with fun FPS gameplay, very linear and derivative, but still plain fun and nice puzzles.
The protagonist is Nathaniel Renko, a soldier sent to investigate Katorga-12, a tiny island controlled by the Soviets. The Soviets find a powerful substance called E-99 which can create formidable weapons and can manipulate time. The TMD becomes an important part of Renko's journey throughout Katorga. You will have to move back and forth between 1955 and 2010 to uncover what the Soviets are doing on the island. As you move around the island you will find scattered audio recordings to fill you in on the plot that appear to be inspired by the Bioshock series. The TMD will help you renew chalkboards to read their contents, renew aged crates to solve navigation puzzles. You can also use the TMD to age crates to solve navigation puzzles, renew old stairs in order to walk up them to reach the next floor, age enemies to turn them into dust, and throw deadlock spheres to get through fan blades that are otherwise rotating. The TMD device is really what's more important than the narrative of Singularity. The puzzles are cleverly done and they force you to use the TMD in creative ways.
While exploring Katorga-12 there are Soviet soldiers who will try to stop you from moving further. There are also mutant creatures that were humans badly affected by the powerful E-99 and will fight Soviet soldiers. Other enemies include Reverts, blind creatures that will detect you only through your noises. The shooting mechanics are similar to the Wolfenstein series and ability to use gravity with the TMD to chrono-pull barrels and other projectiles seem derived from the gravity gun in the Half-Life series. Despite being derivative, Singularity provides a lot of entertainment by having wild shootouts with diverse enemies mixed with bosses. You will have to learn how to use the TMD powers against the enemies at opportune times. Some enemies, particularly bosses and other powerful creatures cannot be aged by the TMD. The deadlock sphere is good for trapping a group of enemies or a powerful enemy, allowing you to shoot with impunity. Mutants and other creatures will pick up explosive barrels to throw at you. You can use the TMD to catch the barrels and throw them back at the mutants. There are diverse weapons including a shotgun, centurion (pistol), auto-cannon, sniper rifle, and a unique grenade launcher. The grenade launcher is one of the most interesting weapons I have ever seen in a video game since you can guide the grenade and make it jump up and down to your liking. All weapons can be upgraded with weapon techs scattered across the island. But the opportunities to upgrade are not very many, so it is imperative to explore to find weapon techs.
The TMD doesn't seem very powerful when you first use it, but it increases in power as you advance and find TMD upgrade machines. You grow to appreciate the TMD device as you become more powerful. A unique firearm is one called the Seeker, a rifle that allows you to manipulate the direction of the bullet you fire. Yes, you can direct the bullet to move up or down, left or right. However, ammo isn't abundant. The necessity to switch weapons frequently helps keep the action fun.
The graphics would have been considered outstanding before 2010, the year the game was released. By today's standards the visuals are decent. But the quality of the visuals does not detract from the fun that the game provides. The game is so linear that if a door closes behind you there is no way of going back to find any items you may have missed. As soon as you reach a save point there is no turning back. That can be disappointing if you missed key items that will help upgrade your weapons, your TMD, or your character.
Singularity is an FPS game with a little bit of RPG that can be entertaining with the possibility of three endings if you play it until the end. It's a good game that does a good job of avoiding monotony by having shootouts with diverse enemies and using the TMD to solve diverse puzzles.
