A collection of various tips and tricks during gameplay.

By opening only a 1 tile wide tunnel to a chamber, a limitless amount of creeper can be held back with a single Cryon, allowing rockets to deal massive damage without much danger.

This strategy gets complicated if other dangers are involved, such as bots. If no bots are involved, shields can serve as a temporary replacement for the Cryon.

Against stationary enemies, it is possible to nullify them through one of these 1 wide hallways, however shields in the hallway will block the nullifier beam.

These hallways also do not need to be straight; so long as the entire path is in range of the rocket, the rocket can navigate through the hallway to attack the creeper. Long zigzag hallways with shields can keep the creeper back for minutes or even hours while still allowing rockets to fire through them.

Your Apex ship starts with 200 energy in storage and a low energy generation rate of 0.30. You want to build as much as you can right at the start to make use of that 200 energy, but if you overbuild that will massively slow down your game plan.

The highest possible economic start without access to starting kirkium is to build 7 reactors, then build reactors one at a time. With access to kirkium, you can start with an extra 1 or 2 reactors depending on how dense the kirkium deposit you are lathing is. Note that reactors take about 2 minutes to pay for themselves; if you intend to win in less than 2 minutes, it is not worth it to build any reactors. In these builds, 2 reactors can be replaced with a digger to get quick access to things like upgrade gems or a large kirkium deposit.

Less economic openings may be needed if the enemy is aggressive enough to need defenses in the first 1-2 minutes of the map. When building up your first set of units, do not let their total costs exceed 200 unless you have access to enough kirkium to make up the difference. Also be aware to take into account supplying units with ammo and the potential for map elements like IXE cores can take some energy from your starting build.
