A Slower Speed of Light is a first-person game prototype in which players navigate a 3D space while picking up orbs that reduce the speed of light in increments. Custom-built, open-source relativistic graphics code allows the speed of light in the game to approach the player’s own maximum walking speed. Visual effects of special relativity gradually become apparent to the player, increasing the challenge of gameplay. These effects, rendered in realtime to vertex accuracy, include the Doppler effect (red- and blue-shifting of visible light, and the shifting of infrared and ultraviolet light into the visible spectrum); the searchlight effect (increased brightness in the direction of travel); time dilation (differences in the perceived passage of time from the player and the outside world); Lorentz transformation (warping of space at near-light speeds); and the runtime effect (the ability to see objects as they were in the past, due to the travel time of light). Players can choose to share their mastery and experience of the game through Twitter. A Slower Speed of Light combines accessible gameplay and a fantasy setting with theoretical and computational physics research to deliver an engaging and pedagogically rich experience.

OpenRelativity

A Slower Speed of Light was created using OpenRelativity, an open-source toolkit for the Unity game development environment. Intended for game developers, educators, and anyone interested in physics, OpenRelativity can help people create, test, and share experiments to explore the effects of special relativity.

Requirements

A Slower Speed of Light has been tested on computers with the configurations listed below.

• Intel Core 2 Duo T9900 or Core i7 (2.8GHz clock speed)
• Windows 7, Mac OS X 10.6.8 (Snow Leopard) or higher, and Linux (Ubuntu 13)
• AMD Radeon HD 6970M/AMD Mobility Radeon HD 4850/Nvidia GeForce 9600M GT
• 8GB RAM

Technical Support and Bug Reports

Please direct bug reports, technical questions, and problems to open-relativity-bugs@mit.edu.

Some users have reported that the game may run on Windows XP and 2GB RAM. A known bug will crash the game on computers with some Intel graphics chipsets (the beta version might fix this issue).

To run the game, Windows users with multiple graphics processors may need to right-click the game’s application icon, select ‘Run with graphics processor,’ and choose the option that is not marked as the default.

To start the game on Linux in a different screen resolution, use one of the following options from the command line inside the game folder, replacing screenwidth and screenheight with your width and height of your screen in pixels:

• 32-bit: ./'A Slower Speed of Light.x86' -screen-width [screenwidth] -screen-height [screenheight]
• 64-bit: ./'A Slower Speed of Light.x86_64' -screen-width [screenwidth] -screen-height [screenheight]
• Example: ./'A Slower Speed of Light.x86_64' -screen-width 1280 -screen-height 720

You can also adjust other Linux game settings from the command line. Here is the full list of command-line options for all platforms.

DESCRIPTION

All New Raft is now out on Steam!

By yourself or with friends, your mission is to survive an epic oceanic adventure across a perilous sea! Gather debris to survive, expand your raft and be wary of the dangers of the ocean!

Trapped on a small raft with nothing but a hook made of old plastic, players awake on a vast, blue ocean totally alone and with no land in sight! With a dry throat and an empty stomach, survival will not be easy!

Raft throws you and your friends into an epic adventure out on the big open sea, with the

objective to stay alive, gather resources and build yourself a floating home worthy of survival.

Resources are tough to come by at sea: Players will have to make sure to catch whatever debris floats by using their trusty hook and when possible, scavenge the reefs beneath the waves and the islands above. However, thirst and hunger is not the only danger in the ocean… watch out for the man-eating shark determined to end your voyage!

Features:

● Multiplayer! Survive by yourself or with friends in online co-op!

● Hook! Use your hook to catch debris floating by.

● Craft! Build survival equipment, weapons, crop plots and more to help you stay alive!

● Build! Expand your raft from a simple wreckage to a buoyant mansion.

● Research! Learn new things to craft in the research table.

● Navigate! Sail your raft towards new places!

● Dive! Drop anchor and explore the depths for more resources.

● Fight! Defend your raft from the dangers of the ocean.
