Detailed walkthrough[]
When traveling with Veronica to find a piece of advanced technology to convince the Brotherhood's elder to listen during I Could Make You Care, one of the options is to power on a secret weapon linked to the HELIOS One power plant. The weapon itself only works by finding the rangefinder tool known as Euclid's C-Finder. For this, travel to Freeside and enter via the east gate. In front of Mick & Ralph's, one will typically find a pair of children running around. The boy, Max, is holding a unique weapon in his hand, the rangefinder, and is chasing the girl Stacey with it while pretending to shoot her. There are several options for acquiring the rangefinder:
Pass a 45 Barter skill check to negotiate the price down to 20 caps.
Pass a 60 Speech check to convince Max the Courier is a space agent come to reclaim the gun, which gets him to hand over the rangefinder for no cost.
Choose the dialogue option to convince him he should go to sleep (may only work after 8 p.m.), then follow him to his resting spot and pickpocket the rangefinder.
Notes[]
It is possible to obtain multiple copies of Euclid's C-Finder, by coming back to Max every few weeks and talking to him; he will have equipped a new version of Euclid's C-Finder which can be bought or pickpocketed again.
Some players have reported that acquiring these new copies of Euclid's C-Finder also resulted in receiving an additional ARCHIMEDES II charge.[verification needed]
