Story

The Xilien have invaded Earth. Unleashing monsters and kaiju on the planet through a spacetime vortex, creatures of all generations attack humanity.

Beginning their assault in Tokyo, Ebirah, Biollante, Megaguirus and other mind controlled kaiju assault the Earth. Mobilizing, a defense force fights back against the invaders using advanced weaponry. Pushing back the alien forces, the Xilien set their scopes on London, Sydney, Arizona and New York while their quest to secure the water on planet Earth is unveiled.

Leveling

Progressing in the game requires leveling up, which is how additional locations are accessed in the game. This is achieved through earning experience after beating Godzilla and the other kaiju bosses. Every time a new level is achieved, an award is unlocked. These awards include:

• Level 2 : Free Card Pack
• Level 3 : Max G-Cell +1
• Level 4 : Unlock London
• Level 5 : Unlock Time Travel
• Level 6 : Max G-Cell +1
• Level 7 : Free Card Pack
• Level 8 : Unlock Sydney
• Level 9 : Free Card Pack
• Level 10 : Max G-Cell +1
• Level 11 : Free Card Pack
• Level 12 : Unlock Arizona
• Level 13 : Free Card Pack
• Level 14 : Max G-Cell +1
• Level 15 : Rare Card Pack (first time only)/Normal Card Pack
• Level 16 : Unlock New York
• Level 17 : Free Card Pack
• Level 18 : Free Card Pack
• Level 19 : Free Card Pack
• Level 20 : Unlock Moon

Level 20 is the last in the game, and no further awards will be unlocked until the player time travels and the rewards are reset.

Moonstones

Periodically during levels, survivors will appear. Clicking on them will rescue that individual, who will be ferried off to the Moon. These survivors can then be sent on mining activities that take a certain amount of real world time, i.e. even when the game is off the countdown will continue. The reward for this is a varying degree of moonstones, which are random between a range. Rewards, needed survivors to perform the task, time and level unlocked are shown below. Note that the Space Titanum artifact increases moonstone rewards. These increase is not factored into the reward totals below.

• Area 1 (Level 3)
  Time: 5 minutes
  Survivor: 1
  Reward: 1-5 moonstones
  
  
• Area 2 (Level 3)
  Time: 15 minutes
  Survivor: 3
  Reward: 6-15 moonstones
  
  
• Area 3 (Level 4)
  Time: 30 minutes
  Survivor: 10
  Reward: 16-30 moonstones
  
  
• Area 4 (Level 4)

  Reward: 141-180 moonstones

Boost
You can decrease the time on a mining task in two ways. The first is by watching an ad, which will cut an hour off the time. This is flat, meaning if the task has less than or equal to an hour left it will be automatically done. This can only be done three times a day. Alternatively, you can pay X-nium to finish the task automatically. The amount varies by the time of the task.

Moonstone Packs
Moonstones are spent to acquire Moonstone Card Packs. These cost 150 moonstones and contain a random 1-4★ card and gold. The gold is based on your total DPS across all open maps, with more gold awarded the more DPS you have. This is tabulated based on your current DPS, so if you use cards to boost damage and then claim your Moonstone Card Pack while the damage effect is still active this will greatly increase the amount of gold awarded.

Missions

Every stage in the game has missions, referred to as "city missions" although they can appear on the Moon as well. There are three missions that appear per stage. When a mission is completed, a new mission takes its place so there will always be three available missions in each stage. The reward for these missions is money, the amount of which is dependent on the type of mission done and the current DPS of the city. For example clearing the "Defeat 3 kaiju" mission will reward with the player with 20 times their current DPS in cash.

Below are the missions available, which are chosen at random. Many of these missions appear in different variants. The tap the screen mission is a good example, as it can require tapping the screen 300, 500 or 999 times depending on the mission given. Note that similar missions can not appear at the same time. For example, if a "Defeat 3 kaiju" mission is currently listed, a "Defeat 4 kaiju" mission can not appear until the earlier one is completed.

	Tap the screen 300 times	$20 x DPS
	Tap the screen 500 times	$40 x DPS
	Tap the screen 999 times	$60 x DPS
	Defeat 30 monster waves*	$20 x DPS
	Defeat 50 monster waves*	$40 x DPS
	Defeat 75 monster waves*	$60 x DPS
	Defeat 3 kaiju**	$20 x DPS
	Defeat 4 kaiju**	$40 x DPS
	Defeat 5 kaiju**	$60 x DPS
	Use 6 cards	$20 x DPS
	Use 12 cards	$40 x DPS
	Use 18 cards	$60 x DPS
	Upgrade bases 5 times***	$20 x DPS
	Upgrade bases 10 times***	$40 x DPS
	Upgrade bases 15 times***	$60 x DPS
	Defeat 3 UFOs	$10 x DPS
	Restore bases 3 times	$10 x DPS
	Rescue 5 civilians (stops appearing after rescuing 644 civilians)	$10 x DPS

*Note: although it says "monster waves" it actually just means regular monsters. So beating a wave of 5 monsters will count for 5 toward this.

**Note: Godzilla, normally, does not count as a kaiju. This means beating him will not count toward the "Defeat 3 / 4 / 5 kaiju" mission. However, this is different on the Moon where Godzilla does count as a kaiju and defeating him contributes to this mission.

***Note: Upgrade milestones, such as at level 400 or 600 when the upgrade button changes to orange or purple, do not count toward the upgrade base task. Oddly, though, buying a new unit does count toward this.

Achievements

There are 49 achievement areas in the game, each with several levels of criteria that have to be met. When met, an amount of X-nium is awarded to the player. Below are the rewards at each level.

3 X-nium
6 X-nium

Day 3:
30 Card Powder

Day 7:
100 Moonstones

Day 10:
50 X-nium

After Day 10, the stamp system will reset begin at Day 1 the next time a login bonus is achieved.

Staff Game

Also noted as a "Credit Mini Game", the Staff Game was introduced in version 2.2.2, which was released on June 25th, 2019.

As the name implies, the game provides full credits for the game. These are shown at the top. As the credits run, the player is greeted to a little mini-game. This sees the player take control of a kaiju and attempt to nagivate through a course. The kaiju is constantly moving during the game, and the player can tap the screen to make their character jump. Characters can jump quickly or do longer jumps, depending on how long the player presses on the screen.

Jumping is required as the course presents obstacles that have to be avoided. The main obstacle are buildings, which appear in three sizes: small, medium and large. In addition to buildings, Rodan will occasionally attack the player as well. This involves the winged monster flying across the screen. He can appear near the ground or way in the sky when performing this attack. While buildings are straight forward, meaning the player just has to gauge how high to jump, Rodan can be tricky as he can either require the player jump to avoid him or keep walking as to prevent themselves from jumping into him.

As the player progresses, the speed of the mini game increases. This results in it becoming harder and harder. Their distance for the particular run is seen at the top of the screen. The distance, or score, is where the player gets rewarded, as an achievement is tied to the game. The top prize, 25 X-nium, requires the player to reach a distance of 1,000 M.

As noted, the player will get to control a kaiju. This kaiju is selected at random. Other than the size, the various characters have no notable difference between them. They include Godzilla '16, King Ghidorah '91, Mechagodzilla '75, Gigan '72 and Jet Jaguar. Below are the five playable characters, along with Rodan.

Note: version 2.2.3 altered the Staff Game, making it easier by decreasing the speed.

Current Errors or Issues

As with most mobile games which see future updates, errors and issues arise along the way. Below are the current bugs, errors or issues.

For Version 2.3.6

• Desghidorah features Mothra Larva's roar.
• Dagahra features Rainbow Mothra's beam sound effect for his roar.
• The Mothra ('92) codex features the exact same text as the Mothra Larva ('92) codex.
• The Godzilla ('67) codex features both the spelling of Minilla and Minya in it.
• The ★★★★★ Fire Rodan '93 has a visual error, where the top half doesn't render properly.
• Placing a second card during battle too quickly after another card overwrites the effect of the first.

Errors from earlier versions waiting to be verified if still present

• Occasionally, when facing Godzilla, the player's army will not attack. This often mixed with an issue where Godzilla and the last monster wave appear together. If the player replays the mission right after this error they will often not be rewarded Time Shards for beating the Godzilla. It's better to leave the location, revist, leave and revist again which will correct the Time Shard issue.
• Sometimes the game will return too many survivors on the moon after a task is done, allowing the player to deploy more survivors than they have.
• The achievement to unlock 10 allies triggers when 9 allies are unlocked.
• On the moon, challenges are given for doing monster waves. However, these challenges are not possible as no regular monsters appear in this location.
• When a large amount of money is accumulated, such as a currency of e254, the game places this on two lines rather than one for the location and moon screens.
• Very late levels on the Moon, such as level 205 and beyond, give no card powder when the kaiju is beaten.
