Event Overview

Overall event difficulty

Since Operation Deep Dive is one of the major events, clearing all levels will be challenging for most commanders. Compared to last major event (Arctic Warfare), the first two chapters are easier, while the third chapter is much more difficult. Therefore, only the first two chapters rewards T-dolls so that new players can also get the most out of the event. New players should try their best to clear E2-4. Those who wants to clear the third chapter must be fully prepared. All types of enemy units are presented in the third chapter. Make sure your echelons can handle all situations.

New game mechanics

Two new game modes are introduced in this event -- rescuing hostages and supply line.

In rescuing hostages, commander needs to search for specific amount of hostages on the map and bring them back to an airfield or HQ. Hostages can be attacked. Each time a normal enemy attacks, hostage will lose one health and the enemy would be destroyed. BOSS unit and the advanced suicide unit (the red ball) will kill hostage on one attack regardless of hostage's health. Please be careful.

In supply line, commander needs to establish a route from the supply station all the way to HQ. Every single spot along the route must be blue for the supply line to be valid, and commander must maintain the supply line for certain rounds. If any spot on the supply line is taken by enemy, the counter will be reset. Please be careful.

These two new mechanics improve gameplay greatly, (Would be more interesting if hostage casualties are ranked. XD) and, in turn, the complexity of each map is increased greatly. However, it provides new way for clearing specific maps. If one is lucky, he/she won't have to confront BOSS to achieve victory. Might be good or bad news for different types of players.

Important: Tactical Fairies

Let me emphasize one: this event is NOT designed based on the new tactical fairy system. Therefore, don't panic if you don't have any tactical fairy. You can definitely clear the event without them.

However, having certain types of fairies does bring certain advantages. There is one type called "air drop fairy", which changes the gameplay to some extent. It provides shortcuts on certain maps which saves you from suffering from "long march". Meanwhile, tactical fairies provide considerable buff to your echelons. This will come in handy when clearing the third chapter. Also, if you plan to try out the ranked battle after chapter three, tactical fairies would definitely provide great helps. Therefore, if you have spare resources, it's highly suggested that you build some of them.

Operation Bomber Ball

(I don't know what the name is referring to) To deal with the red suicide bomber, the most feasible way is to run away from them as far as possible. If you try to confront them, in most cases, you will get destroyed. The only bomber we need to defeat is the black suicide bomber, which drops supply crate. And commander will spend a lot of time trying to catch them.

Also, this event maps consists of a lot of one way circle. It's very annoying and complicates the gameplay.

Tips for new players

You MUST learn how to change the position of your T-dolls during battle! If you don't know how, ask those who knows! BOSS is invincible while using skills. You should get used to it.
