Achron, a real-time strategy game focused on temporal mechanics from indie developer Hazardous Software, is currently in an alpha testing phase for pre-ordering customers as development continues.
By pre-ordering a license to Achron, you can download the latest alpha release, and all the upcoming future releases of Achron, including the full final game. Other pre-release programs available to those who pre-order include mod tools, tournaments, community artwork submissions, community level submissions, the Resequence Engine, and possibly third party Resequence time travel games. Please see our release calendar, frequently asked questions, and end user license agreement for further details.
It’s a neat (and fairly unique I believe) idea; moreover, the gameplay itself requires elaboration:
Achron is the first game to feature single-player and multiplayer free-form time travel. It is the world’s first meta-time strategy game, a real-time strategy game where players and units can jump to and play at different times simultaneously and independently.
You can undo your mistakes, change your strategy after committing to it, preview the future, freeze time to perfectly coordinate attacks, and send entire fleets through time to when they are needed. However, all of your opponents will also be independently moving across time, attempting to rewrite history in their favor…
There are additional gameplay videos illustrating the core concepts here; as a sci-fi nut for pretty much, like, forever, I plan on making the time for this ASAP.
While there is a recent super-high-profile RTS release that shall remain nameless, I encourage you to at least read about what Achron is attempting (here’s a good preview from earlier this year at Ars Technica). There’s also a blog entry concerning the process of porting to Linux.
