okay dispite not playing long i could see that without a doubt the one on roblox is so much better than this i played and just kinda chilled the entire time learning the buttons examining the terrain, you know seeing how it worked. well it works trash i now understand why no one plays. theres nothing to stop you if you run into a rock you go through. some of the buttons don't make sense and those who saw the comminuintys post all those cool looking colored animals well sorry your beyond limited. Also theres no one to play with I was quite litterly the only one playing. this game did better on roblox where a child i added did more and made it better than grown adults who think they can pride themselves on something like this. this is my own thought yall have your own too get at your own choice

nice game in general the animal models are cool and realistic tho the animations of them needs to be focused on more, the nature pretty as well but would be nicer if there were more emotes instead of just laying down, i couldn't check combat as there are not many player to do so but really cool game overall!!!

Boltgun 2 price: buy the sequel, or the cheap first game?

The Boltgun 2 price has no cheaper route on launch day — our record shows one listing, unmoved since September. The first game is the bargain, but a smaller one than it was.
