Start the assault! - Interstellar Rift Development Update 120

Performance upgrades! So after searing the patch for a bit for the past week in the experimental branch we have determined that the optimizations seem to improve performance for a lot of people. That said, its not the only thing we are adding this week.

Introducing the PR-61 Plasma Rifle! This new personal defence device can be printed or bought at select LogiCorp tool stores. Holding 40 shots in a single ammo canister. This piece of offensive and defensive technology will make short work of any undesirables you come across.

The new plasma rifle can be fired in full auto mode or in single fire mode by tapping the fire button on your mouse. The file and its ammo can also be printed similarly to how the pistol and its ammo are made. You can find the full recipe in the patch notes.

For a full list of bug fixes please see the patch notes linked below.

As always, we’d appreciate any feedback you’re willing to provide, it will only help us make the game better. We have also set up a public discord server which you can join!
Feel free to drop by and have a chat, we’d love to hear your opinion and feedback!

Thank you all for playing and see you starside!

Interstellar Rift is a First Person Starship Simulator with an emphasis on open world exploration and multi-player interaction. Players will need to survive in a hostile galaxy with their own custom designed and constructed starship. Space is vast but you wont have to face it alone, other players will be able to join you aboard your ship to help you man your vessel’s more complex devices and equipment.

Customize your ship

Our ship design tool will allow players to quickly create or modify existing ships to suit any possible situation. By mining and gathering resources from across the galaxy you’ll be able to construct more powerful and efficient components so you and your ship can face any challenge. Equip drone bays, to have a fleet of autonomous helpers, or build the enormous strip miner, to extract resources from rare large asteroids. From a small shuttle to a large warship, every ship can be what you want it to be.

Explore the galaxy

Help out factions to gain their trust and spread their influence throughout the universe. Build new stations, defend them from invading alien forces, or destroy them to lower a faction's influence. Build a rift generator to travel to other solar systems, and repel the alien forces to prevent them from taking over sectors. Whether you're flying a large cargo hauler, a capitol battleship, or a mining barge, there will always be missions available that match with your ship. Venture out to find rare resources to build special equipment, or buy special items that can be sold for profit. Interstellar Rift is build to suit any play style.

Advanced ship simulations

Building your ship is only the beginning as it will require plenty of work to keep running. You will have to manage your fuel and power levels, keep systems from being infected by alien parasites, make sure devices stay in working order, and much more. Players who are in a crew can rely on each other to maintain the ship, and for solo players there are automation options such as the ACTR (automated cargo transfer relay), to help out with the heavy lifting.

A threat beyond measure

Throughout the galaxy, mysterious rifts are opening up, spilling out a dangerous alien race called the Skrill, that when left unchecked will seize control of the region. Players must band together to stop these enigmatic invaders before they threaten the safety and profits of their enterprises. Between the dangers of pirate drones, vicious Skrill, and other human players, pilots will have to be on a constant lookout!
