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.
Mod, cheat or hack tracking tools:
Let's start with what the tools are showing:

So most of these tools are incredibly heated, signaling that they are showing available mod, hack or cheat for the game.
Wendgames chatter:
Here is some of the chatter from various comments on this site and facebook groups since the release:

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.

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.
