Recent updates
Wavebreaker Outpost Event and new Design
- UI: Beta Layout: Introduced a new Beta Layout available in settings, covering buildings, research, production, weapons factory, defense, economy pages, fleet command, Alien Waves, Interdimensional Transmitter, planet bar, and live resource display.
- UI: Interdimensional Transmitter: Updated Transmitter page to show detailed overview of extra bonus every 10 activations and transparent display of possible rewards and chances, reflecting existing values.
Changes, Updates and new Outpost!
- Recycling Yard: It is no longer possible to use the Recycling Yard via Merchant+ if an attack is less than 60 seconds away to prevent harassment attacks.
- Merchant+: Merchant+ now exchanges resources when starting research if the required resources are not available.
Forum Migration and Game Changes
- Forum: The forum will be migrated to a new server separate from the main server structure to improve availability even if Bitmeup servers have issues.
- Rubblefield Event: Fixed a logic error where global rubblefields were not adjusted by universe speed, causing excessive farming values.

SpaceInvasion 2
SpaceInvasion 2 is the newer, more cinematic version of the game. Our community loves the classic retro style so much that we focus mainly on SpaceInvasion (Classic) — but if you prefer the more modern look, SI2 is right here to dive into.
