Solos are a playable Class in Cyberpunk 2077.
Solo classes provide the opportunity to play as a lone mercenary character, working as a hitman, bodyguard, or anything else that pays well and offers violence. Many Solo variants have a military background, whether national or within a corporate army, and many sport cybernetic prosthetics in place of lost limbs.
Primarily fighters, and essentially Cyberpunk 2077's answer to the warrior or DPS class, Solo classes take advantage of Skills in a wide variety of weapons and both armed and unarmed combat proficiencies, as well as combinations of heightened perception, stealth and athletics.
The Solo class' signature ability is 'Combat Sense', giving them an increased sense of imminent dangers, traps and general harm.
