It is by far the most valuable Polygon in the game, awarding 13,000 worth to your score when destroyed. A player killing it at Level 1 will directly rise to Level 37. In Domination, Tag, or Survival, killing this Polygon can allow the player to rise to level 45 almost immediately, due to the 2x score and 3x score, respectively, Experience gain bonus in those Game Modes.
When you are killed by this shape, it will say “You were killed by: Pentagon” instead of “You were killed by: Green Pentagon”.
It has a third of the health of an Alpha Pentagon, making it the second most durable polygon in the game.
Like other green Polygons, the Green Pentagon's color code is 0x89FF69.
Unlike Alpha Pentagons, it doesn't just spawn in the Pentagon Nest although it is more likely to, as more Pentagons spawn there.
Even though it is more common for these to spawn in the Pentagon Nest, it still isn't very common.
You can change normal pentagons into Green Pentagons by changing their color with a Console. However, it will still function like a regular Pentagon.
