**Invader Arrival Chance** The annual chance of an invasion by the Invaders is changed to a new formula. For v2.5.1 the chance is: 5% \* (Years Since Invaders Activated / 20) \* (Increment Length / Year) The new version is: (Largest Rift Diameter in million km ^ (1/3))) + 2%) \* (Increment Length / Year) For example the annual chance after 30 years of invaders (assuming usual 10% per year growth). Old: 5% \* (30/20) = 7.5% New: (175m km ^ (1/3))) + 2% = 7.6% The annual chance after 50 years of invaders (assuming usual 10% per year growth). Old: 5% \* (50/20) = 12.5% New: (1174 km ^ (1/3))) + 2% = 12.5% The reason for changing the calculation, even though the results appear to be similar, is that I am going to add some options for increased invader threat by increasing the size of rifts. The new formula will increase the invasion chance based on the increased rift size. **Enhanced Invaders** v2.6 adds an additional option for Invaders. This is a separate checkbox called ‘Enhanced Invaders’ and will only function when the normal ‘Invaders’ option is active. If Enhanced Invaders is active, there is a chance that a new Aether Rift will be larger than 10m km. The 10m rift will appear 60% of the time. For 30% of rifts, extra 2-100m km will be added to the diameter (rolled as 2 x 50m) and for the remaining 10% an extra 2-1000m km will be added (rolled as 2 x 500m). As the chance of invaders appearing and the size of the fleets is based on rift size, this can lead to much larger invasions earlier in the game. --- _[View the full topic](https://aurora4x.com/t/aurora-v2-6-0-patch-notes-september-6th-2025/23)._
