Small Star to Black Hole Progression

The concept behind reaching the Black Hole stage as quickly as possible, forgoing the options of building up a multi-star system or 10 planet solar system, is to rapidly consume as much planet mass as possible. The method behind doing so is much like in the Planet stage with some key differences.

Gaining mass as a Star

Instead of now capturing asteroids to consume for mass you will need to capture planets, while more sparse, are easier to capture than asteroids are for planets. This is mainly due to their slower relative speeds compared to your star and the gravity well you possess than can be used to capture them effectively.

Life Planets will of course offer the most mass upon consumption but can be beneficial by also shielding your star while you go about growing larger. You will need at least 2 Life Planets with at least 3 turrets on each before the shield becomes active over your star.

Finally the one important note is that keeping your solar system small will allow you to find more free floating planets as growing a large solar system will cause larger objects like yours to spawn and less smaller objects like lone planets. Also make sure you don’t spawn a second star by consuming too much asteroid mass on one of your planets, unless going for the betrayal achievement below.

Betrayal Achievement

Shown in the video below, the process in unlocking the Betrayal achievement in Solar 2 is much the same as growing a single star system to a black hole but just takes twice as long to do. Mass consumed is always evenly split between your stars with whichever one is the smallest having the priority in consuming the next planet. In other words there is no way to turn a neutron star into a black hole while you still have a Small Star or other smaller star as it will consume all the planets you eat until it is of equal size or larger.

One other challenge besides just having to consume more mass is the additional Life Planets you need to maintain a shield around your stars. A good way to determine how many life planets you need for Star Shields is to take the number of turrets currently on all your orbiting planets and divide that number by 6 and round it down. The number you get is the maximum amount of stars that can be shielded meaning 12 turrets across all your planets are required for a dual star system shield.

Invader Missions

The invader levels in Solar 2 are somewhat similar to the Nomad Love missions you faced as a planet, this time around facing larger amounts of forces that come in waves. The strategies for these group of missions is the same for each, with the only difference between the levels being a progressively larger amount of ships to deal with.

Generally speaking, you can spawn as a max life solar system, which you should have saved from use in the other missions and solar system building walkthroughs, and just duke it out with the aliens that attack you using your lifeform spaceships and turrets.

One important tactic is to always move around when a new wave shows up, as they typically gang up on a single one of your planets. You want to dart around to break up the attackers and get them interested in your spaceships versus your planets to avoid losing the extra life spawned by it. You can also try to get them interested in any nearby hostile solar systems or Life Planets. Other than that, the tactics here are pretty simple and straightforward.

*This mission group is part of the index due to its relative simplicity in explanation.

This is not very helpful to my need. I am looking for a tutorial on how to go from a small star to a medium star. It's because it says Planets:3/3 but it won't let me advance. If you find anything email me please at jsyarbrough@hotmail.com.

Thanks in advance,

Jamie
