BEWARE: The company uses a BAIT and SWITCH strategy where at lvls 1 to 9, the grind is ok but at lvl 10 and up, the game will match you with top 100 ships or ships that have almost no resource(gas). At endgame, it literally requires billions of gas to level up legend crews and also after a few weeks, theyll introduce a legend league wherein theyll limit the total number of attacks to 20, severely limiting grinding and making it the same as other mobile games with energy cap. BEWARE
