Super Time Force

Players have 30 lives to run through bullet hell levels. When the player dies or voluntarily ends the run, the player can view and rewind their timestream to revisit the life of a prior player-character's run or otherwise restart with a new run. There are over 16 different characters in each of the 6 stages with different weapons or powers of their own. In addition, the player can also use items like cloxs (clock items that reverse the time limit), shards (violet dust-like pixels that allow the player and the game's time limit to pass in slow motion; they are only visible if the player uses the "Time Out" mechanic) and glorbs (yellow diamond-shaped items that increase the player's number of lives by one, and are found on every level on certain areas or in enemies that are difficult to capture). Both shards and glorbs can be collected to unlock a new character when a certain number are obtained.

Commander Repeatski sends the Super Time Force, a time-traveling military organization, to various points in history such as prehistoric times, the Middle Ages, and the future in order to make the present a better place to live.

The game stems from a three-day experiment at the Toronto, Ontario Game Jam in May 2011. The game jam event coalesced hundreds of Toronto-area game developers to build quick prototypes around a central theme: the phrase "what just happened." Kenneth Yeung of Capybara and artists Mike and Vic Nguyen brainstormed as a three-person team and decided to make a time-traveling side-scrolling shooter, "a Contra game where you can go back in time." This quickly became the core feature, where upon death, the player fought "alongside ghost versions of themselves doing what they had just done before they died."

Dying created co-op partners of the player's recorded actions. Yeung described it as, "Gunstar Heroes meets that one level in Braid."

Super Time Force received favorable reviews from critics for its story, characters, colorful pixelated graphics, references to pop culture, and the unique ability for players to rewind back where they left off after their character dies using its game mechanic on each level's area as its checkpoint.

Game Informer's Matt Miller praised its playability and explained, "the reimagining of how we perceive time in an action game is what makes it memorable." Critics have pointed out some mild flaws in that its repetitive life-saving throughout the game's time-out layers was seen somewhat confusing and overwhelming, but still found its gameplay an enjoyable experience. Kotaku commented that the game "[f]eels a lot more tactical and technically impressive than it initially appears", and also added that "[m]anipulating time in video games isn't a new thing, but the way that STF uses the gimmick feels fresh and clever. Rewinding and playing through a chunk of game over and over creates hectic layers of action. It's chaotic but beautiful."

Super Time Force Ultra, abbreviated as STFU, was released on August 25, 2014. It features over 50 mission levels via the "Helladeck"; the Steam version of the game features guest characters owned by Valve, such as the Pyro and Saxton Hale from Team Fortress 2 and Zoey from Left 4 Dead. The PlayStation 4 and PlayStation Vita version of Ultra features Sony Computer Entertainment chairman Shuhei Yoshida as a playable character along with The Traveler from Journey and Sir Galahad from The Order: 1886.

Jean Rambois makes a cameo appearance in Mercenary Kings when the player can encounter him and receive a new weapon, while Zackasaurus appears in Indivisible as a playable character. Several characters from Super Time Force are also featured as part of a downloadable skin pack for the sandbox game Minecraft.
