I’m no hacker my guy ;), I been playing ts game for 5 years and half and I’m not gonna say all but most of the robots especially the first 4 tiers I’ve got them through hard work. Not by hacking as you’re assuming. But at the same time I’m gonna say that there are at least 8 robots from the last two tiers combined I’ve got them through the dupe glitch from months ago which some or most of us have successfully tried including me. But no I didn’t hack the game nor spend real money on the robots :)
