I'm gonna tell you some tips what I would love if someone told me before I started playing

1. Do you want to get to the top of a mountain, but no short way or either grass on the rocks?
Just hold 'W' and fast-tap the "space" key. Your hero will start jumping forth through the rocks and won't slide down.

2 Do you need to get somewhere but no teleportation point near that place?
Open the map and zoom in until you will see little blue pins (like a typical location icon), left-click on it and press 'F". After paying respect you will be teleported to that place and it will economy your time. Those signs are a lot, on the map you just need to zoom as much as the game lets. Don't make my mistakes.

3 Keep money for an elite class sniper rifle. You will one-shot the enemies. Even more, you'll kill bears with two shots. The best weapon in the game IMO.

4.Tip. Don't arrest Seed in the very beginning for having an easter egg. Just stay AFK, don't press "enter" and the cut-scene will begin.

Thanks for your attention, cheers.

P.S. You may revive Marshal in the prison just shoot him and he will get up.
