I am hoping stealing it stealthily is an option. I hope the game does not need to strictly lay out every single path you can take in the mission objectives, but lets you discover them organically.
Yeah absolutely, because in the demo once you get the mission from Dexter, the player can then go about it how they want to complete it.
Main mission - Talking to Dexter to get Militech Flathead.
Optional - Meeting the Corpo grants the player 50k cred chip.
Optional - Use cred chip for personal gain or use virus against Maelstrom Gang.
Optional - Talk your way into Maelstrom gang, sneak in, take by force.
But none of this is required from what I understand. The end result is getting the spider bot regardless how hard the player makes it on themselves. Instead, use the 50k cred chip and buy a ton of gear if possible, break into gang hideout and wipe them out, or stealth in get the bot.
Using the cred chip virus on the gang is only to make an alliance with Corpo, but isn't required.
