Diep.io higher tiers and upgrades explained (advanced)

In my previous post about the latest free to play multiplayer tank game, Diep.io, I mainly talked about how the game works and what to do if you’re just starting out. I also briefly mentioned the first tier that can be unlocked when reaching level 15, but in case you didn’t know, there’s plenty of more upgrades and tiers to gain so in this article I will explain what you can achieve in the game once you reach the pro gamer levels.

Also note that If you are unable to access Diep.io directly due to your host’s restrictions which is very common in workplaces and educational institutions, you might want to check out one of the diepio unblocked websites or simply use a free web proxy like ProxySite, although the connection there can be very slow.

Tier 2 and beyond

There are a total of 4 main tiers in the game starting with tier 0 (the starter tier) and each new tier can be unlocked by gaining an additional 15 levels. For example you will unlock tier #1 when you reach level 15, tier 2 at level 30 and tier 3 at level 45 which is currently the final tier that can be reached.

With every new tier that you unlock, you get to choose an upgrade for your tank. Needless to say, those upgrades make you better, faster, stronger and harder to kill.

Since I already explained the first tier in my other article, I will start with Tier 2, but you should know that you are stuck with whichever upgrade you decided choose at level 15 so it’s advised to think it through carefully in the beginning!

You can only choose an upgrade in tier 2 and beyond based on the upgrade you chose at tier 1 (level 15).

Diep.io Tier 2 explained

This tier will become available to you after reaching level 30 and with it come new upgrades to your base tank model taking you this much closer to becoming an invincible killing machine.

Twin shot upgrades

Reach level 30 with the Twin Shot upgrade from tier 1 and you get to choose between either the Triple Shot, which gives you a triple barreled gun, or the Twin Flank, which acts exactly as the flank guard from tier 1, except you now have two barrels.

Machine gun upgrades

If you chose the Machine Gun from tier 1, you now have the option to further advance it by choosing between the Destroyer, which fires slowly, but packs some serious weapons damage, and The Gunner, which is an advanced form of the Triplet and has two long barrels instead of one.

Sniper upgrades

When you reach level 30 with the Sniper upgrade, you can turn it into either an Assassin, Overseer or the Hunter.

The Assassin will improve your weapons range, damage and bullet speed just like the Sniper, but it’s way more powerful than its 1st tier counterpart.

The Overseer is an interesting choice and one of the most dangerous enemies to be around when you’re a newbie because it can summon up to 8 red triangle minions that the player can control with their mouse and kill almost everyone easily. It can also be used as a type of shield by circling the triangles around yourself.

The Hunter shoots projectiles the same way a regular shotgun does by firing out a bunch of small pellets from a single barrel that spread around the area in front of you. Anyone caught in between the blast will find it very difficult to maneuver between the bullets.

The only downside with the Hunter upgrade is the fact that it can’t be further improved when reaching tier 3 at level 45.

Flank guard upgrades

With the flank guard upgrades, you get to choose between 3 ways to advance your tank:

  • Twin Flank – Has two barrels at both sides of the tank.
  • Tri-Angle – Gives you two smaller barrels at the back and one main barrel in the front. With this upgrade your tank will become faster due to the two extra guns that boost you forward which makes it easier to chase down your enemies.
  • Quad Tank – This one has guns on all four sides of your tank and is one of the most impossible monsters to escape, especially if you’re a small beginner tank. With this upgrade you are guaranteed to crush many foes.

This covers all the upgrades available at level 30 with the 2nd tier. If you are interested in reading about Tier 3, you can subscribe to my newsletter and I will let you know once the article is out, or you can simply read the detailed Diep.io wiki page about Tiers for yourself.
