Disrupting the Nebula is the huge new update for FISHLABS' Galaxy on Fire - Alliances. The update has a ton of new features such as the new tactical sector grid, which segments the game world and gives you info on hot spots on the star map.
Battles have been upgraded so that they now come in multiple waves. You'll have breaks between the differnt rounds to send reinforcements or order your fleets to retreat. And if you're looking for an edge in battle you can now rely on your spy drones to collect info - not just on planets, but also on enemy fleets.
The game also has a bunch of new social functions that will make it easier to invite friends, a global in-game chat, and push notifications to quickly call for allies.
And to celebrate this big update, FISHLABS has even opened a new server for the game. So if you want to try out all the new features, you can download Galaxy on Fire - Alliances for free now.
