When you start a new game, you will be presented with three different options. You can skip the tutorial, change the difficulty, and/or select Ironman mode.
- The tutorial will guide you through the battle process, fleet deployment, and room construction. If you skip the tutorial, you will start at Day 0 without a Diothrium reactor.
- Higher difficulty levels result in enemies having more health, doing more damage, and spawning more frequently. This also applies to station bombardment. Resource production from facilities is decreased, but this is offset by the potential to get more resources from the extra battles.
- Ironman mode keeps only one save file, instead of the normal rolling save files. It disables officer re-rolls but does not affect achievements. This option will make mistakes more costly, since you cannot back up and try again.
