About this game

The last bunker stands on a contaminated planet.
Develop skills, merge them, and deploy units to defend against monsters attacking from every direction.

■ Random Skill Development
Skills are generated randomly during battle.
Use Pyro, Frost, and Electro skills to fend off the incoming monsters.

■ Merge to Grow Stronger
Merge skills of the same tier to obtain higher-tier skills.
Even low-tier skills can become powerful combat resources through merging.

■ Complete Combinations to Deploy Units
Each unit requires a different skill combination.
Complete the required combination to deploy powerful units that will join the battlefield and help defend the bunker.

■ Endless Waves
The monsters never stop.
Repeat skill generation, merging, and unit deployment to survive increasingly intense attacks.

■ Grow After Battle
Use battle rewards to upgrade your units and skills.
Return with stronger forces and break through higher waves than before.

Craft randomly, merge smartly,
and summon units with the right combinations.

Start defending your bunker now!

I'm loving the game so far, have recommended it to a lot of friends, and love all the updates you guys have been putting out. The only thing stopping me from giving you 5 starts is that the Boot Camp quests are broken. The only 2 quests I'm missing are the "craft x skills", which are stuck at 1 no matter what I do. I really want to finish them and get the last reward, but I can't. Can you please help me?

Bug: localisation/translation issue when I click on unit and the +, I see Chinese/Korean? text. Feedback: Often I end up with 28 skills unable to advance because they are 1 or 2, but you need 3 to merge and 28 is the max. Even when % rate boost is at max, I get too many common and uncommon skills and eventually get stuck. I would suggest increasing or get ridd of the skill max altogether and check if there is an error with, or adjust % rate boost. Add in-game feedback. Otherwise I like the game.

Lowest Budget + High Profit, thats the dev aim. 2D, Minimum Control, Wrong name (No Tap tap), no offline reward, no cutscene, no story, no control, no detail from enemy, no detail from our guy, stupid bot (Fire bot keep hitting imune fire enemy, and so on), downgrade while upgrading or combine, and you know what, its so expensive top up.. twice or triple regular game.. and no ads only a month, like scare we will play it for 10 years, lol. totally boring repetitive
