When I tried the army guy, it wasn't for too long, but he was probably better at close combat than shooting. I also tried Ghost and played with her as a companion for a while, but then I lost her at trader area because I forgot that they disappear there. Well, we weren't really close to that trader base, but she ran straight towards the area and poofed. I guess that just happens sometimes and you lose your coins, it was a nice run while it lasted though. I've been getting some NREs with them, so to be perfectly honest, it's hard to fully enjoy with console errors showing up in the middle of a fight. Her animation is glitchy sometimes and she stays static, but her body moves around and then moments later it fixes itself somehow and her animation works correctly again. At one point I saw that she had the lower part of her body under ground, but teleport solved that issue.
