UFO

There are four UFO easter eggs in ninja.io. The first UFO is in the Canyon map. This is only reachable via the "infinite" flight function/glitch and/or M79 boosting. You can only stand on the edges of the ufo, standing on any other part will kill you. The bottom of it is very bouncy. and has pieces of terrain floating in its beam. In CTF, players sometimes hide the flag here.

The second UFO is in the Cathedral map. This is only reachable by knocking the balls out of the hot air balloon and standing in the basket to float up¹. Be careful as after you knock the balls out it will go up very quickly. This one is harder to reach as it involves not being killed while knocking the balls out and and then getting up to the basket. Once on the Ufo, it will slowly/instantly kill you depending on where you stand. the middle section will instantly teleport you back to earth and full heal you. The third and fourth UFO is in the Tribal map. They are both reachable via the "infinite" flight function/glitch and/or M79 boosting. They have 3 beams: two white beams that propel you off in their respective directions, and a red beam that damages you. Standing on the UFOs instantly kills you.

1. Some cases have been reported of reaching this UFO via M79 boosting combined with the "infinite" flight glitch.
