All charisma and endurance, be the bimbo fuckslut of the wasteland.

800x600 is the best resolution for a number of these old games, that way the text and menus and stuff aren't super tiny for ants. The original Homeworld has the same problem if you play on the really high resolutions, the menus and text just don't scale up to fit with the new resolution. 800x600 is better than the normal resolution of 640x480 and the text/interface looks ideal at that size.

Start with unarmed untagged, raise it to 150 manually, the take the tag perk and you'll have 300 unarmed making you a literally unhittable god in combat thanks to HtH Evade

Bonus: If you take Jinxed the enemy will kill themselves attacking you, critically missing, and hitting themselves.

If ammo is the issue, then use Bozar instead.

It's manageable on a 1920x1080 screen.
