Great physics and sandbox game but aircrafts are all restricted to a realtively low flight speed. Might just be because the maps are kind of small and not super condusive to fast-moving flying vehicles

Jan. 2025

so far my 2nd fav game. this game is kinda hard at first and complex but u can figure it out by either yourself or ingame tutorials and if you do not care about how hard the game is like me then this is a perfect game.

most fun ive had playing a sandbox/machine building game definitely recommend to anyone who's looking to get into these kinds of games and wants a smooth introduction to them

Sept. 2024

Things I really like about the game consist of driving vehicles since they feel super nice and enjoyable, I wish a lot of car games handled as well as the vehicles in this because it is really really good! I also love the customization and vehicle creation though a lot of the tools aren't obvious unless you go through or look up the tutorials. The multiplayer aspect with a variety of shenanigans to get up to is always enjoyable as well! Although... Aircraft and spacecraft are pretty bad since there's only button keybindings so you can't use mouse to control, and it also makes combat very difficult. Also the fact that the devs stopped developing the game in 2021 makes it hard to recommend but if you enjoy what's here like I do then it'll definitely be a game I recommend picking up but only if its on sale!
