# Space Attack vs Alien

The clearest difference is in-app purchases: Alien at none against Space Attack's 7. Alien also leads on ads (none vs shown) and update cadence (every 10 days vs every 4 weeks). Space Attack's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.6). On price there is nothing between them.

Both are free to download. Space Attack sells 7 one-off in-app purchases. Alien asks for nothing beyond the download.

Space Attack ships an update every 4 weeks, Alien every 10 days. The most recent releases landed on October 8, 2026 and October 14, 2026 respectively.
