Sharing Some Tips While Progressing Through 9-1

Your main body level is shared, so it's best to maintain the highest possible level. However, if Robot 1's max level is 100 and Robot 2's max level is 150, and you use Robot 2 at level 150 then switch to Robot 1, only the max level of 100 will be applied. Regarding weapon equipping, it's more beneficial to fully upgrade 2-3 main weapons rather than equipping all 5 types. Weapon leveling can also be reset, so you can level up various weapons and then choose the ones that suit you best. In my case, I'm using the Meteor Cannon (the one that creates black holes?) and the floating capsule weapon, only equipping these two. I only really need to control my character during boss fights (the 5th boss of each stage) and zombie rushes; otherwise, I can clear stages with just sustained damage. The level-up options you choose during stage progression are also quite important. It depends on the weapons you have equipped. For my Meteor Cannon, I've chosen upgrades like split, increased pull, and increased frequency to scatter enemies. For the capsule weapon, I've gone with offensive conversion, freeze, increased count, and increased duration to freeze mobs and prevent them from clustering in the center. Hope everyone clears 10-5 and gets their coins~
