I spent a while looking at the code for crate odds and I believe this is what it is:

• If there are no enemies alive, the function returns cash. This is a default or fallback behavior with there are no threats and its hard to break a crate with no enemies
• If the player's health is less than 25% of their maximum health, the function returns health (testing and experience have shown that this isnt always true)
• If the player's health is at least 25% of the maximum (e.health / e.maxHealth >= .25). Then the weighted random selection process picks the index 1 from the array b, which corresponds to the freeze bonus (e).
• this can be between 7.5% and 50% chance of a freeze depending on ammo amounts I believe the best odds are full health and full ammo

I think this can help because it would mean that breaking a the first crate on level 3 with minigun so that shotgun still is full would have a 50/50 chance instead of a small chance of shotgun ammo. idk tho still need to be tested

I know on Awesome Tanks 1, they have a 100% category, along with newgame+ and any%. I have thought about adding a 100% category, wanted to know if anyone would speedrun it. Also would like to ask about change the name from clear file to any%.

I have just become a new mod, will work on getting the runs approved now.

Just recently uploaded a video to my youtube channel that is a spliced run of the two fastest NewGame+ runs. I timed it at a 3:58.060, which means that it is possible to get sub four in this category. I think good menuing can cut a lot of time, and good luck on getting good ammo drops on the crates and the main luck parts. Here is the link
