GalCiv IV: Supernova Dev Journal #87 - Megastructures: Stellar Gateways

More Megastructures!

The latest DLC for Galactic Civilizations IV arrived earlier this month, introducing a host of powerful new Megastructures. In this week's dev journal, we're diving deep into another of this expansion's titular Megastructures: The Stellar Gateway.

Stellar Gateways

Stellar Gateways are massive portals that utilize the reality-warping power of black holes to create connections between distant points in space. These powerful Megastructures are ideal for expanding to distant corners of the galaxy, establishing extended trade routes, or rapidly redeploying fleets.

Stellar Gateways are unlocked by the "Advance Nexus Augments" technology and are the third Megastructure to be unlocked by the DLC, following Dyson Spheres and Stellar Nexuses.

Stellar Gateways are constructed around the perimeter of black holes by new Stellar Architect ships using a resource called Gigamass. Each Gateway takes 8 turns to construct.

Building a Stellar Gateway requires 30 Gigamass, a finite resource collected by Planetary Harvester ships from dead planets. Each additional Gateway requires another 30 Gigamass, so you will need to consider the benefits provided by a new Gateway pair compared to other similarly priced Megastructures like Stellar Nexuses.

Once a second Gateway is completed, it will automatically pair with the first. Sending a fleet through one Gateway in a pair will instantly transport it out the other. Additionally, fleets will automatically consider Gateways when pathfinding/looking for the shortest route to a location.

To make navigating Stellar Gateways easier, we’ve added a convenient button to the Gateway Context Window. Clicking this button will instantly move the camera to and select the other end of the Gateway pair.

As you build more Gateways, you may want to reorganize, break, or form new gateway pairs. This can be done easily from a new tab in the Automation window accessible from the main screen hot bar.

Note: Stellar Gateways can be invaded and captured, and thus will need to be defended.

Fleets can be stationed on Stellar Gateways by turning them “on” or “off” via this toggle on the Stellar Gateway context window. While turned “off”, fleets will be stationed on the Gateway instead of being sent through - allowing you to fend off any would-be Gateway thieves. The Gateway’s current state can be seen at a glance using the icons overtop the Gateway itself. A Gateway being “off” will not prevent fleets coming through from the other end.

Transportation Network

As stated before, Stellar Gateways are excellent tools for expansion, trade, and warfare. The ability to funnel new fleets straight from shipyards to far-out frontiers can be a game changer. Additionally, consider that the reverse is true - a military on campaign can return to the defense of your otherwise undefended core worlds and capital in a fraction of the time it would normally.

Having a strong network of Stellar Gateways can also be a diplomatic boon as you can establish the new Gateway Treaty with your allies - allowing them to use any of your Gateways and you theirs.

A well-placed Gateway will let you take your enemies by surprise with an invasion launched far behind enemy lines or it can allow you to resupply your invasion force with no delay. Altogether, Stellar Gateways are a powerful tool for any playstyle. The increased mobility that even a single pair of gateways provides can be extremely useful - especially on larger maps or games with multiple sectors.

As you explore the new features of Galactic Civilizations IV: Megastructures, consider the strategic possibilities offered by the Stellar Gateway. Whether you're expanding your empire or bolstering your defenses, the Stellar Gateway provides a versatile tool to enhance your civilization's strengths.

We invite you to share your favorite new strategies with us. How will you leverage the power of the Stellar Gateway to shape your galactic empire? Will you focus on rapid expansion, military dominance, or perhaps a thriving economy? The choice is yours, and we can't wait to see the creative ways you'll use these Megastructures to achieve victory.

Stay tuned for more insights and updates in our future dev journals. Until then, may your civilizations prosper and your stars shine brightly!
