Private Kowalski

Kowalski is an NCR Private encountered in Boulder City in 2281.

Background
His brother, Donald Kowalski, died at the battle of Hoover Dam. When the player meets him he is on leave and plans to go home to see his family in California, but before he goes on his way he wanted to pay his respects at the memorial.

Private Kowalski does not remain at the memorial indefinitely, and will disappear from the game world some time after the player resolves the events in Boulder City.

Other interactions
Note that 'desecrating' (shooting or otherwise harming) the memorial will make a speech prompt and, depending on your selection, may make him become hostile. Killing him will give NCR infamy or cause others to attack you (the latter not confirmed). If you pass the Speech check, and you shoot or harm the memorial again, he will not open fire. Calling him and his brother a "bitch" will cause him to become hostile. punching the memorial may damage him personally and cause him to attack you (xbox / spiked knuckles)

Appearances
Kowalski appears in Fallout: New Vegas.
