Lemnis Gate unfolds at some unspecified point in the far-flung future, with humanity on the brink of extinction. In an attempt to postpone its fate, Earth has built a massive interstellar device which, once activated, will sling the planet back in time by 50 years. Unfortunately, a whole heap of parallel universes have had the same idea and are now engaged in battle to be the one to turn on the device and be the reality that survives.

Tactical cunning is key to victory in a game where skilful shooting meets turn-based strategy over five time-bending rounds. Take turns changing the future as multiple timelines converge. Set ambushes, fix past mistakes, and bait opponents into committing their own in an ever-shifting match of temporal tampering.
