UI is old and looks outdated.
No weight classes.
Scale of size is terrible.
You can only move at one speed.
You have to very precisely move components into place as there is no snap to grid function.
You can not edit a bot once you've uploaded it to the Steam workshop.
Components can go outside the chassis.
Components can be overlapped with ease.
You don't need a control board to wire up a robot.
The online functionality is broken. The host always wins.
You can move before the game starts when in online play.
Servos and burst motors stay in the air when moving the start/finish and therefore cannot be judged easily.
Parts can go through the robot during gameplay. (I was able to break the burst motor basically)
You can't make a two wheel robot properly.
The chassis can be distorted to be put through itself.
"Havok" explosions have happened on multiplayer.
Camera constantly moves down in the bot editor at times.
Camera angles have to be changed via mouse.
The skinning system is terrible and needs to be reworked.
Train runs robots over, does no damage.
