A Level 1 Tank will need fifteen hits to kill a Green Square. This results in a reward of 66.67 EXP per hit.
If you manage to destroy a Green Square at Level 1, you will skip the next 15 Levels, instantly landing you at Level 16.
A Necromancer can make this Polygon one of its Drones by crashing into it or touching it with its current drones. The resulting drone will be the same as a drone made from a Yellow Square. However, the green square drone will give you EXP when it is killed, unlike other drones.
When you are killed by this shape, it will say “You were killed by: Square” instead of “You were killed by: Green Square”, as they are practically the same thing, only the Green Square is much rarer.
The Pentagon has the same HP as the Green Square, which is 100 HP.
Although they have the same health, the Green Square is easier to destroy, as their base body damage stat is different (which will reduce the damage taken when a bullet hits them), with the Green Square having -3 body damage with 0% damage reduction (same as Square) and Pentagon having -2 body damage with ~33% damage reduction.
It can be found in most likely 2 Teams, Domination, 4 Teams, and any other game mode. It is much rarer in Sandbox mode because the map is smaller and it won't have much room to spawn in.
