It’s very easy to waste your money in this game and if you do, you’re essentially out of luck when it comes to buying the weapon upgrades that you actually need. The most useful upgrades are the ones that increase the power of your weapon, because it’s literally impossible to play stages in Royal Hills or after Royal Hills (when you return to Bumville Shores and Central) until your weapon has enough power.
The butt stock and the scope are two of the less useful upgrades in the game. Even though the scope helps you see through fog, there will never be so much fog that you can’t see.
As for the butt stock, that will decrease the movement of the weapon before you shoot it, and the muzzle will decrease the recoil, but both of those aren’t absolutely necessary. They are only needed if your vision isn’t good enough that you can’t see through the fog, or if you don’t have a steady hand.
The single biggest waste of money is buying either the MSR-S or the Sleazy Luiz. Don’t buy either one of those. Their stats are the same as the M16 before it’s upgraded, meaning that you will have to make even more money to spend them on upgrades for those two guns. Just stick to the M16, and keep upgrading it.
The magazine might seem like a useless upgrade on the surface (unless you don’t like to hit the reload button), but the better your magazine is, the more you can upgrade your bullets. More upgrades on the bullets means more power, which again means less having to compensate for wind and distance. With your rifle body and bullets fully upgraded, you won’t have to do ANY compensating for distance or wind.
After doing the time lapse cheat, if you want to set the recovery time for your energy and for the freight back to normal, simply close the app before you set the time back to normal. Then open the app back up after you set the time back to normal, and all of the cooldown times will be back as they were.
