OF-EX6 Event Mission - Tips To Win

Multiple Ways To Clear

Multiple Ways To Clear

There are multiple ways to clear OF-EX6. All rely heavily on the player's placement and immediate answer to threats, so there is always a constant need to be attentive to enemy waves. Also, you need to have at least 1/3 of your team to be Elite 2 to clear this one.

Split Method

Use the blocks to divert the enemy waves into 2: middle and top. The top lane separates the Heavy Defender Type-N and Infantry Leaders from the middle, giving your Operators there some space. The top lane requires only a Defender and a Caster. On the other hand, the middle lane requires a lot of Guards and a Medic to sustain.

All Mid Method

All Mid Guard

In this strategy, all of your Operators are placed on the middle main lane. All enemy waves are funneled through this, so concentrate as much damage as you can on 3-4 tiles. This requires Elite 2 Guards with a couple having ranged capabilities such as SilverAsh and Thorns to back up the front line.

Defeat The Ergates Fast

Defeat Ergate

The most annoying enemy unit in this map are the Ergate leaders. These guys are unblockable units and are highly resistant to Snipers. Use Caster to combat them before they reach your base. Also, make use of the Blocks and use them to temporarily block paths to your base!

Ready A Decoy

Ready a Decoy

All methods rely on a single unit, either a Defender or Guard, to take damage and stun from the Snipers. The Sniper Leaders that spawn in this map stun the first Operator they see or the latest one that spawned. Have this unit on standby to get the stun to protect your main line from breaking.

Ifrit's Map


If you have the ★6 Operator Ifrit, you can use her capabilities fully on this map. You can have her on the upper right side of the map for maximum coverage.
