The Alpha Octagon is supposedly a re-work of a removed Octagon, with changed color. It was supposedly added in late 2019. On September 27, 2019, it's health was nerfed. As of October 19, 2020, Led Zeppelin is no longer able to push these.
The Alpha Octagon is a large purple octagon that is about as large as an Alpha Pentagon.
The Alpha Heptagon has 600 health and gives about 24000 experience upon destruction. It can only evolve from Alpha Heptagon in the pentagon nest. Alpha Octagon may evolve further into Alpha Nonagon in the pentagon nest. It evolves commonly, but also can commonly stay as Alpha Octagon. Alpha Octagon has a higher resistance compared to Alpha Heptagon, that's it takes less damage and is harder to kill.
If you have reached a higher tier like fourth or third tier, you have some chances to destroy Alpha Octagon. If you find one and can destroy it, you may consider it as an excellent source of experience, and it will be probably worth the time you will attack it. Alpha Octagon can also give a lot of experience to the players with highest tier, and they may destroy it if they have high DPS. You can also use Alpha Octagon in defensive purposes against Bots, if you are unable to defend by yourself. In this case, you can move behind Alpha Octagon and trick bot into ramming Alpha Octagon and taking massive damage. This will force the bot to retreat.
