I think lone wolf could of been a hell of a lot better if there were multiple ways to end it (all resulting in you dieing). Like if you die rather fast, it shows him not putting up much of a fight, or if you last more than a set amount of time, the ending changes to show him running out of ammo and just getting overrun. All branches of the ending tho would result in him dieing, so it doesn't necessarily change the fact he's dead other than how he died.
