Yeah, just pick up
the "Apogee" Sandevistan. People talk a lot about other steps you can take to optimize the build--adding the
Axolotl Cyberware for cooldown reduction, using Scalpel for guaranteed crits, or later on, using Byakko for insane attack speed once your crit rate is high enough--but really Apogee by itself is good enough to trivialize most content in the game, on Very Hard difficulty.
There are many ways to become overpowered in this game, but as far as I can tell Sandevistan+Katana is the current "meta." That combo has the best mix of perks and Cyberware bonuses. With the amount of mobility Katana offers, its melee-range restriction isn't even really a measurable downside. You can just spam dash and strong attack with the gap-closer perk and you'll magically fly to your target.
Here's an example.
I can't say whether this build is
exactly as powerful in Cyberpunk 2.0 as it was in prior versions; it's true that you can't achieve near-perma-Sandevistan
passively,
anymore, but you can still become ludicrously strong. The same applies to netrunners, which now take longer to bloom, and require a little more work than they used to in the moment, but by level 40 or so you're right back to remote-killing whole buildings full of mooks from across the street. Probably the main overall difference in the balance of power is that Berserk builds can also now get insanely strong, though not as strong as Sandy/Deck builds.
