>can someone let me know if it's possible to completely solo my way through all of the game?
Sure. If you git gud.
But the game doesn't exactly "end" at any point. It's a very easy pick-up-n-play sort of game, honestly meant for co-op.

Starting Solo to learn the basics is a good way to get going, but you really should get some friends / jump into public games.
There's zero competitive elements. Everyone gets 100% of all loot and EXP, and the more players play and survive, the bigger the bonus. Besides, you don't even need mics nor text chat to communicate effectively in DRG; just spam your Laser Pointer + Salute at everything, and you'll do fine.

it's jolly cooppan' at its best.
Don't get tricked into playing some Haz 4-5 turbo sweatshop missions too early. That's the fastest way to ruin all the fun, especially if you're more into exploration than killing shit.
