>do your quests to get free guns from commander level up
>add friends with strong friend echelons to carry you through story mode
>unlock up to 7 or 8 available squads with gems (IAP currency)
>get 4 squads constantly doing logistics to farm resources and crafting tickets
>max out 2x 3AR2SMG teams before moving to HG/RF or MG/SG teams
>don't bother using HGs as tanks until you get them to level 80 where they can equip exoskeletons
>don't bother with heavy construction or MG/SG teams early unless you want them to eat all your resources
>ignore enhancement pill combat sims once you unlock the memory frag sim at commander level 60 since the game showers you with them via events
>farm memory frags on pill days while you max out eligible guns
>always do skill sims and exp sims
>don't try unorthodox squad setups if you can avoid it
>use battery to upgrade your data room ASAP and don't waste it on pets or cafe shit
>make battle reports as often as possible if you can afford it
>each gun transfers small % of exp gained to global exp which is used to make battle reports
>level 100 guns transfer most of the exp they would've gained in combat to global exp
>battle reports cost 3 battery and 3k global exp each
>add friends and collect free battery everyday by visiting their dorms
>avoid prioritizing expansion of 4*s and 5*s early until you have plenty of cores or dupes
>duplicate guns can be used to save 1 set of cores when expanding unit size
>after unlocking enough squads use gems to buy raifu/equipment storage, more dorms, or wedding rings, prioritize according to immediate needs
>don't bother with buying more construction/repair/training slots unless you have money to burn
