## What is NGU Mecha battle?

The world has been overrun by cyborgs, robots, and mechanical mutants (whatever that means). Your survival depends on the power of your combat mech. In pursuit of glory, you'll have to defeat thousands of creepy-crawly and overly ferocious creatures. Battle Robo-Mouse, blast Cyber-Cockroach and his girlfriend into smithereens, test your skills against Techno-Moose, or skewer toothy Synth-Spaghetti on a fork.
Game Features:
o	Idle and off-line gameplay: Leave it offline and return later to find progress waiting for you. Progress happens continuously!
o	Upgrade your mech in various ways: Visit shooting ranges, participate in hunts, enhance gear, build weapon factories, or reboot your mech's firmware to boost its stats.
o	Use experience gained from battles to level up abilities.
o	Stuck fighting a boss? Use DESTRUCTOR or GAMMA-BURST. These and other boosts will instantly increase your attack power or weaken the boss' armor by one-fourth.
o	Maxed out everything but still stuck? Reboot your mech and start fights anew with fresh energy and make your battle even more epic.
o	Four main skills: Attack, Defense, Health, Repair for epic survival.
o	Multiple locations unlock as you advance, each more challenging than the last.
How to Play:
Upon entering the game, your first opponent is Mouse. It’s harmless and can be defeated within seconds. The next boss isn't so easy though. Before taking him down, you need to up-grade your mech a bit. Head to the shooting range and distribute energy between skills. Each skill bar fills up gradually strengthening them. Once you're stronger, it's time to tighten some bolts on those uppity metal dudes. Enter battle mode and bravely attack Rat Dad. Next comes three more cyborgs before reaching Hunting Grounds. Here, you can relax a bit cause we've intentionally placed the stupidest monsters for your first few battles. So, don't waste any tears, dismantle these creeps piece by piece while collecting their loot and craft powerful battle items. Consider this freebie loot, cause after this, you'll have to fight fierce opponents for better gear and the drops won't always give what you want. 

I suppose I've explained enough now to scare you off! It's true, this idle RPG game is only meant for the brave! If you've read all the way here, make sure to complete the tutorial at the end where you'll receive five extremely important Tetramorphs—it’s in-game currency. That's it, no more chit-chat, let's go to battle!!
