Cosmolot's Space Invaders UFO adds a variable bonus element to every wave, the UFO's crossing timing is periodic but its point reward is randomized on each successful hit.

Some UFO hits yield modest bonuses while others yield exceptional rewards, making consistent UFO targeting a high-variance scoring strategy that is worth pursuing in long sessions.

Players who can reliably time UFO shots while maintaining their formation clearing rhythm gain a meaningful cumulative advantage in extended high-score sessions.

In Tournament mode, a particularly high UFO bonus can swing the Space Invaders contribution to the combined score significantly, adding an exciting variable to tournament results.
