there are top secret 5 entities that you cant get normally lol
you can break them by exploding them, overheating them, overcooling them and you can break them by shooting at them




this is the ninja that looks like player 2 and just runs around like zombies but he doesnt attack you and he's fast like players (unlike zombies)








this is the car entity on the first frame after you spawn it, you can't enter it so all it does is just roll








this is the car on the next frame, still does nothing











this is the sled, when you try to enter it you just fall and sleep until you exit it, cant control it with movement keys, it also DOES slide, can be seen in sand:box stickmen update trailer, was cut from the game since alpha testers said that it didn't look fun



this is the box entity, no much info, like all other entities, doesn't have collision when touching any entity, looks cool though, might be nice for building some maps, yet its not easy to just take it out and spawn lol (actually it's not that hard if you know what to do)




this is the ... uhhhh.. wait what is it called? stick? tree branch? ... ok guys so i dont really have any info about this one but people call it stick entity, im not a developer or some alpha tester so yeah theres almost no info about these also thanks to fumG for discovering these first
btw theres a fourth and fifth view modes that might be not released yet or just for debugging (especially fourth view mode)
and here are some screenshots of them:






all 5 unused entities in liquid nitrogen, this 4th view mode has something to do with temperatures





at the left there is steel material with a temperature of 20°C, a bit to the right, there's steel with very high temperature, and at the right there's steel with very low temperature, a bit lower from the middle there is flame under the 4th view mode and a bit higher from the middle there is fire under the 4th view mode





and this is the 5th view mode, everything becomes red.
