''[=TimeShift=]'' is a 2007 ScienceFiction FirstPersonShooter game developed by Saber Interactive and published by Sierra. Their second game after ''VideoGame/WillRock''. The general plot is that the Bad Guy, Dr. Krone, uses a prototype time-travelling suit (known as the Alpha Suit) to go back in time and rewrite history as they see fit, with the protagonist (an [[MysteriousPast unknown "scientist"]]) travelling back to stop him in the Beta Suit. Is notable for its focus on time altering powers.

A sequel was heavily hinted at during the end credits via messages from the Beta Suit's computer, and there was a very appropriate CliffHanger ending, but it never materialized.
!!'''This game provides examples of:'''

* ArmorPiercingAttack: The Hellfire's bullets automatically set enemies on fire after a couple of shots, which serves as an insta-kill 90% of the time. This is very useful in the later levels, where enemy soldiers are tough enough to soak almost a full clip of regular assault rifle fire.
* ASpaceMarineIsYou: You're ''supposedly'' a scientist, but it doesn't take a rocket scientist to figure out that something is amiss. [[spoiler: Cutscenes reveal that you're in fact a government spook planted to keep an eye on Krone.]]
* AwesomeButImpractical:
** The Alpha suit is the root of the Beta suit, which is prototype of a design that is supposedly being designed for military use. Apparently the army are sane enough not to give their soldiers the ability to travel back several decades.
** Gameplay-wise, the time-reverse ability. It's extremely cool, and obviously took a lot of time and effort to program correctly, but it simply doesn't have any usage in regular combat gameplay other than unsticking sticky grenades. It's basically just for solving the occasional puzzle.
** The Surge Gun. It's an incredibly powerful [[ShockAndAwe electroshock weapon]] that fires energy balls in the primary mode, and a constant stream of electricity in its secondary. Unfortunately, you can't refill it from ammo crates because it uses an energy cell instead of conventional magazines; the only way to refill ammo is to kill the rare Warp Guards who possess it. In fact, the only time it becomes useful is during the final boss fight, and you have to use the weapon's primary mode to defeat it. Fortunately, the weapon crates in that level infinitely provide you with the gun so that you won't be in danger of running out of ammo.
* BilingualBonus: Krone is German for Crown.
* BlatantItemPlacement: Mostly avoided but miniboss fights always have the appropriate weapon nearby.
* BookEnds: The ending takes place at the same location and point in time as the intro.
%%* BoringButPractical
* BulletTime: An essential game mechanic. Unlike [[VideoGame/FirstEncounterAssaultRecon F.E.A.R.]], where its use was optional, you pretty much ''have'' to use it to get through many of the game's quite hectic firefights.
* ChangedMyJumper: While some people will make comments about your 'fancy suit' no one seems that bothered.
* ClothesMakeTheSuperman: The Beta suit, a wearable time machine with lots of special features.
%%* ColourCodedTimestop
* ContinueYourMissionDammit: The Rebel Commander keeps radioing you to stop delaying and get on with the mission, ''even if you're moving through the level as fast as humanly possible'' [[note]]''and even if you're slowing time to move as fast as superhumanly possible''[[/note]]. Although probably due to a timing bug, this ends up making him seem like a huge JerkAss.
* DifficultyByRegion:
** The "Normal" mode of the console versions is actually the "Easy" mode of the PC version. Presumably this is to compensate for the less precise aiming of the controller vs. a mouse-keyboard setup.
** There's a bug in unpatched versions of the game where the helmets on Krone soldiers (the guys wearing green armor) don't work properly; as a result, they can be killed with a single headshot. This makes the later levels significantly easier. For some reason, the UsefulNotes/{{Steam}} version of ''Timeshift'' still has this bug, even though it's supposedly patched.
* DoNotDropYourWeapon: Averted, enemies can drop weapons if shot and you can simply take them after freezing time. At which point they appropriately panic.
* EliteMooks: Some of the Krone soldiers encountered in the later levels have subtly different armor, and are much more durable, being able to survive almost a full clip of assault rifle fire or even a direct hit from a rifle grenade (although they can still be killed quickly with late-game weapons like the Thunder Bolt, Hellfire, or Surge Gun). Many of them also carry E.M.F. cannons.
* EnemyDetectingRadar: green allies, red enemies and yellow quad bikes.
* EverythingSensor: "Concealed threat detected."
* ExcusePlot: Not intentionally, but when the rights transferred (see ExecutiveMeddling), apparently Sierra didn't see fit to complete the storyline.
* FacklerScaleOfFPSRealism: The gameplay is generally ''VideoGame/FarCry'' influenced (three weapon only carry system and a few hand grenades) but with several differences. First, you are clad in a PoweredArmor with time-bending powers similar to ''VideoGame/{{FEAR}}''. Unlike ''FEAR'', you have a more complex time-bending system ([[BulletTime Time Slow]], [[TimeStandsStill Time Stop]], and Time Reverse, all [[ColourCodedTimestop Colour Coded]] [[ColourCodedForYourConvenience For Your Convenience]]) and it is pretty much ''mandatory'' to use your time-bending powers as playing the game in an old-school, Rambo-like manner will get you killed very quickly, thanks to how EXTREMELY aggressive the AI is and how VERY fast-paced combat is. There are various puzzles in the game which pretty much require your time-bending powers to pass through and with careful amount of precision. Your suit has shields that can regenerate as long as you are in cover and not taking any hits. However, your health is static and your health is a whopping one unit of health, meaning taking any hit when your shields are out is instant death. Finally, because of the one unit of health, there are no health pickups to come by, forcing you to use strategy.
* FeaturelessProtagonist: Done intentionally, so that the player is technically the character. Original builds of the game actually did have a defined main character, but this was dropped to raise the immersion.
* FlashStep: Thanks to the ability to slow and stop time, half the fun of the game is doing this to the regular {{Mooks}}, who get understandably freaked out by the sight of you teleporting and running at superspeed. This gets reversed when you run into the Quantum Guards (namely the Flash and Warp Guards), who can do the same to you.
* GlassCannon: You can carry various weaponry and dish out all the damage you can to take down {{Mooks}} while in your time-bending Beta Suit, but its shields are rather weak and once they're out, [[OneHitPointWonder you're toast in one hit]].
* HarderThanHard: Elite difficulty.
* HeroicMime: You!
* InfiniteSupplies: The ammo crates placed in strategically distant places in each level seem to have a bottomless supply of ammo for ALL of your weapons, barring the Surge Gun.
* {{Jerkass}}: The rebellion leader is incredibly far from polite and thankful during gameplay, considering you are pretty much the ''[[ItsUpToYou sole reason]]'' they are getting anywhere in their resistance efforts, though this is more of a case of AnnoyingVideoGameHelper due to bad programming. He's actually a pretty decent guy in the actual cutscenes, but during gameplay he'll often radio you the same 2 or 3 "Get your ass in gear!" lines [[WelcomeToCorneria OVER]] and [[MostAnnoyingSound OVER]] again, even if you're going through the level as fast as humanly possible.
* KillItWithFire: The aptly-named Hellfire sub-machine gun, which not only spews out incendiary rounds, but also has a ''built-in flamethrower''.
* MeaningfulName: "Krone" sounds a bit like the Greek deity of time, Chronos, doesn't it?
* MysteriousPast: Cutscenes reveal that [[spoiler:you may in fact be a plant; a special agent sent to keep an eye on Krone ''just in case'' he tried this.]]
* NonstandardGameOver: If you screw up during the fan puzzle in the Test Labs level, you'll get a special animation showing your character being sliced up by the blades.
* ObviousBeta: A lot of the in-game loading screens refer to missing features, and the rewind power is disabled a lot to prevent minor bugs; they "justify" this as a security measure.
** The concept is good, but they could have done so much more, both with the time powers and the general setting and storyline.
* OneManArmy: You, obviously. What with your time-altering suit and all. [[LampshadeHanging Lampshaded]] in one later level where one of the {{Mooks}} says, "What, just one guy?"
* PoweredArmor: Your time-bending Beta Suit.
* RailShooter: The two zeppelin sequences.
* RegeneratingShieldStaticHealth: Although an unusual example since that static health is a [[OneHitPointWonder whopping 1 unit of health]], which means taking any kind of hit will kill you if your shields are at 0%.
* SecondHourSuperpower: The first suit you get
* SchizoTech: The result of Dr. Krone's meddling. Giant (literally giant) robots with lightning guns, scifi-esque gunship/transport aircraft, and all sorts of other things, in the year 1939.
* [[ShieldBearingMook Shield Bearing Mooks]]: The Storm Guards, who you'll encounter about halfway through the game, wield energy-reflecting shields that absorb anything that you throw at them except rockets and grenades. Using the [[TimeStandsStill Time Stop ability]], however, causes their shields to disappear entirely, making for an opportune time to kill them.
* SmashingHallwayTrapsOfDoom: A sequence takes place in a factory, but you can (or rather, have to) just BulletTime or TimeStandsStill your way past most of them.
%%* SoLastSeason
%%* SpaceFillingPath
* StickyBomb: Clutch grenades. These can OneHitKill all but the most powerful Mooks, and you if you're playing Elite difficulty.
** Also, the Thunder Bolt's rocket darts.
* SuperpoweredMooks: The cybernetic Quantum Guards; there are 3 different types (Flash, Storm, and Warp), and 2 of the 3 have a special time-bending ability similar to your own. The only non-time-bending superpowered Mooks, the Storm Guards, [[ShieldBearingMook actually use shields]] not unlike the Jackals from ''Franchise/{{Halo}}''.
* SuperSpeed: Slow time is effectively this, though for the player it is basically BulletTime until halfway through the game when the [[SuperpoweredMooks Flash Guards]] show up to run circles around you in normal time.
* TemporalParadox: What happens if you're crushed by a reverse moving object with Time Reverse.
%%** The end of the game.
* TimeStandsStill: One of the three time powers you can use in the game is the ability to freeze time.
%%* UnnecessaryCombatRoll
* VeryHighVelocityRounds: Bullets and even explosives act normally for you with both the time slow and time stop powers. Somewhat justified in that the fluff says the suit affects your weapons as well as you. This gets... interesting (read: fun!) if you rewind time whilst sidestrafing and firing.
* VideoGameCrueltyPotential: Seeing as you can slow down, stop, and rewind time, this is a given.
* WhereItAllBegan: The final level is the same as the tutorial level, but since you've spent the rest of the game changing history leading up to that point, things are radically different.
* ZeppelinsFromAnotherWorld: And they're pretty AwesomeButImpractical [[CoolAirship zeppelins]] too.
