Warning: This guide is based on using a cheat code to enable god mode and to give you enough photons (money) to purchase everything in order to unlock all the achievements as quick as possible. If you have issues with using built-in developer exploits, I suggest you read no further and play at your own leisure. For the purposes of this guide, it will be assumed that you are using the cheat code.
"Of Tanks and Demons III - it's the new game with the vibe of classic arcades of 80's. Collect photons, shoot demons, buy new tanks and improve them. Don't rely on brute force solely! Sometimes you need to outsmart your enemy, not just outgun them with bullets.
At the end of 2020, the worst thing in history of mankind has happened - gates of Hell has opened and let the hellish hordes of demons run wildly on Earth. For the hellspawns, the human weapons were not much of a threat. It looked as though the human race had no hope left for survival. But in the darkest hour the glimpse of hope, the ray of light appeared, and so it happened: the group of American scientists, with Dr. Gusev as their lead scientist, invented the special photon cannons that can easily tear demon flesh apart. New photon weapons were installed on advanced tank models, created by Greenrunner Industries Corporation. But there was a problem with tanks; they can be operated only by those who created it. These people were genius engineers of their time, but when they opposed the government they were imprisoned as war criminals. Facing the total destruction of all life on Earth, the government decided to make a compromise. Now there is only one way for Travis Greenrunner and his people to get their freedom back - to drive away the demon scum to the place they crawled out from!" - microsoft.com
This game plays similarly to Pac-Man where you have monsters chasing you around a maze while needing to pick up pellets (called photons). The level ends when all of the photons are collected. Once that happens, the remaining monsters are sucked into a portal and a shuttle comes to pick you up. There are also five bosses you need to defeat as you make your way through 23 levels.

In order to enter the cheat code, at the main menu, select ‘New Game’. Then press to return to the main menu to see that a ‘Continue’ selection is now there. Enter (with the D-Pad) then press and a new menu will pop up on the screen. Here you can turn on ‘God Mode’ and give yourself photons. Then select ‘Continue’ to advance to the level select screen.
Before moving on, press to enter the Shop. You need to purchase all five tanks, from left to right, to unlock three achievements. Then press to return to the level select screen and choose the first level. When you do, you can upgrade your tank fully for two more achievements. When you are done, press to play.
To earn the rest of the achievements, you simply need to play through Level 23. With ‘God Mode’ enabled, this will not be difficult at all. Just move around the maze collecting photons and eliminating monsters. You have limited ammo and nitro but a shuttle will be deployed to drop more of each sporadically to replenish both.
Note: In order to collect the large photons, you need to capture them, which takes approximately four seconds.
Aside from the three bosses you need to defeat to earn achievements (in Level 3, 8 and 23), there are two other ones you need to defeat as you progress to the final boss:
- Devastator - Encountered on Level 15. This boss takes about 12 hits, but doesn’t take damage when on the pedestal
- Dendroid - Encountered on Level 19. This boss takes about 15 hits, but doesn’t take damage when it’s twisting
Playing the game as intended, I don't even want to speculate how much longer or more difficult this game would be. As with many Victory Road games, the provided cheat code makes this game for us achievement hunters a breeze to play. Congratulations on another 1000!
