I am hearing some rumors being reported today after seeing a spike in chatter within the gaming community on today. I have not seen the third-party game tracking tools show this much rumor in a long time. I will say the tracking tools are way more heated than the chatter I am seeing, so something might be off here. Again, I saw some initial chatter from within the gaming forums and on this site starting on today.  Now, I decided to cover it on everyday even if the chatter was not at the levels that would warrant me posting something.
To be clear, Wendgames' radar has not confirmed any release is officially going on.

Holy shit this is the biggest gaming news of the year

I surprisingly knew about this game's existence before this!

From someone who actually played it, it's fine, just a pretty average  game. Unless you're chomping at the bit for new experiences, if it looks interesting to you just play the first one.

Game description:
The game starts with the selection of a leader for humanity’s survival. The leader in the Zombie Crusade has the ability to rewind time upon death. Whenever they are defeated by zombies, they go back to 5000 B.C. However, the experience and resources gained from battles with zombies remain, serving as the foundation for creating the next civilization. By studying the processes of inventions and discoveries that had a significant impact on human history, you secure the technology to develop civilizations and establish a new civilization on the land overrun by zombies.

Depending on the inventions and discoveries obtained by the leader, you can strengthen the military power of the civilization created in the zombie world. From primitive huts and cavemen in 5000 B.C. to knights, cavalry, and musketeers, create a variety of soldiers and upgrade them to become more powerful.

The only way to protect humanity from zombies is by constructing a stronger civilization.

* How to play:

1. Choose a leader to build a civilization. Initially, you can start the origin of humanity from a nameless tribal chief in the land overrun by zombies.
2. Start researching on topics that have had a great impact on human history with the available resources, or upgrade the leader’s abilities.
3. Enter the zombie world and defend your base by increasing the number of soldiers or upgrading them.

* Features:
1. Unlock new soldiers or upgrade fields based on the researched topics.
2. When you upgrade the leader’s abilities, all soldiers in the new civilization start from the leader’s abilities.
3. All soldiers automatically attack and engage in combat with zombies within their line of sight.

* Soldier Control:

1. Touch a soldier or select one soldier, or press the “Select All” button at the bottom of the screen to select soldiers.
2. When there are selected soldiers, pressing the pause button will make them stay in place and attack zombies within their range. Pressing the play button will allow them to move freely again.
3. Press the “Return” button, and the selected soldiers will move back to the base.
4. When resources are scarce or the population is high and you cannot create more soldiers, you can select soldiers and exchange them for resources.

Develop your civilization, defeat more zombies, and save humanity!

In any case, the best mod, cheat or hack for now comes down to these tips:

1. The first cheat or exploit is to not skip the tutorial, even if you're an advanced player and this is your second, third, or fourth alt account. The beginner's tutorial gives you lots of free stuff and rewards, which are some of the most valuable items in the game.
2. Keep watching the ads and collecting more and more daily currency rewards.
3. Play daily events for more chances to get better currency.
4. Practicing to get better time in PVE or offline mode.
5. Don't skip any unleashed events.
6. Use ad packs from the store to get currency. And free packs can be obtained every certain number of hours.
7. Watch YouTube or Twitch videos: gamer's gameplay style and tutorials.
8. Play against many different opponents with many different gameplay styles.
9. Join the game community on Discord, Reddit, Facebook, or other social media platforms where you can share your gaming experience.
10. Are you a competitive online mobile gamer? The secret to becoming a top mobile gamer is to first have at least a medium-range phone or a top-of-the-line phone. Without a good device, you will never be a good gamer. Next, you need a superfast internet connection. If you want to do exploits against other gamers online in real time, you need incredible internet connectivity, or else lag will become your best friend when your ping goes up to over 300 ms. And finally, you need to be me, Wendgames, the greatest mobile gamer the world has ever seen. If anyone else tells you anything else, they're lying. Skills only come through persistence with great devices and fast connectivity to react appropriately against enemy players.
