While 9th Company-Roots of Terror is an interesting little strategy game, it sadly suffers from a bunch of bugs, I seem to have worked out how to avoid them, if you encounter any other bugs/ways to avoid them, message me.

The AK74U doesn't share ammo with the full size AK nor can it get AK ammo from the AK ammo crates, since no enemies use it, this makes AK74U ammo extremely limited, I therefore do not recommend using it on most levels, while it does weigh less than the full-size AK, it's a difference of only 0.3 Capacity, it's not worth the inability to re-stock ammo outside of friendly units.

Your troops need to use up a full magazine of ammo (30 for the AK74U, 60 bullets for the AK74, 10 SVD rounds, 8 Makarov rounds or 100 PKM bullets), and reload to be able to pick up more ammo at all. (So someone who only fired 6 AK bullets cannot pick up more.)

The pick-up ammo command will always go for the closest source of available ammo for that weapon, this means troops will trade ammo with each other instead of picking up more ammo from dead bodies usually if the alive friendlies are closer, so move your troops closer to fallen enemies/away from each other to pick up ammo from corpses first.

While you normally are unable to pick up any weapons during a mission (With the exception of Turrets/Mortars and vehicle weapons.), you can pick-up grenades if you have an empty grenade slot and enough weight to carry them. (So an PKM User with the heaviest armor who can't bring grenades into a level can infact pick-up grenades once he's used a PKM Belt or two and has the spare weight to pick them up.)

The Difficulty Options effect damage for everyone it seems, so playing on Private will also make the enemies take more damage, I'll need to do more testing to confirm for sure.

This is more of an one-off tip, but Enemy Snipers (SVD and Lee Enfield) carry Makarov Handguns, while I've never seen them use them yet, you can search dead snipers for Pistol Ammo. (Since no ammo crates containing any show up outside of the tutorial.)

The AI in this game makes no attempt to avoid friendly-fire, I highly suggest turning off Friendly Fire if you don't want your units instantly killing each other by shooting their friend in the back of the head at a point-blank range.

A bug in the English Steam version (Russian walkthroughs online do not have this bug however but I'm unsure if this is due to them being Physical or some bug unique to the English digital version.) makes it so that vehicles without drivers can still move on scripted paths/when ordered to by the player as well as attack enemies of the previous user automatically in the case of Tanks.

Go to your game files then the DATA Folder then open config.ai with notepad and search for TankIgnoreDrivers and set it to false, now this bug is fixed and vehicles will properly no longer move without any drivers.

"Vehicle is moving" bug for entering turrets, the turret is still trying to "Aim" at one of your soldiers due to an error when the enemy using it was killed, move any soldiers nearby til' you find the one the turret is tracking and have them move far enough away it can no longer see them, you should be able to get on the turret now, this is also fixed by the TankIgnoreDrivers fix.

While it might seem cosmetic at first, Vehicles that catch fire are actually slowly draining health, while you can still use them for a little while, they will eventually explode so make sure to get your vehicle crew/passengers out before that happens.

There's no means of repairing vehicles, try to make sure they don't get hit by RPGs if possible but don't worry too much about losing them since they don't carry over between missions.

Pressing F12 Hides the Hud, this will make the menu screens entirely blank, simply press F12 again when this happens.

Pressing the U key messes up the screen, just like the F12 thing, just press U again to fix it.

To Enable the Cheat Console, got to the DATA Folder in the Game files then open config.cfg, search for showconsole then replace false with true, the cheats are:
SetAdditionalFireSupport() Additional artillery support for next mission
God (0, 0) God mode
God (0, 1) Unlimited ammo
Win () Victory

Save game bug
If you save and quit mid-mission, if that mission has a automatic bit where it moves the Camera later on, the game will fail to pan the camera/update your objectives and you'll get spammed with objective messages that pause the game, it's therefore best to just play the missions in one sitting to avoid this bug.

You can freely load the auto-save after completing missions (at the map screen) without issues.


43KM Mission
You cannot save and load for the first half of the mission or the triggers will bug out after you beat that, you'll get a defend section.
To defend against if the mission doesn't end properly.
You need a save roughly 12 minutes left on the survival timer. (this is what worked for me, don't worry, there's no more camera pans so you can safely quit and try again later if it doesn't work.)
So, you beat this mission and seemingly nothing happened? well that's the result of a bug, after a certain point, the enemy is supposed to panic and retreat, which wins the mission however sometimes this doesn't happen.

So either load a save you made earlier before the timer expired or restart the mission. (Alternatively you could use the mission complete cheat or the cheats to spawn friendly units to steamroll the mission that works without enabling debug mode.)


Prisoners Mission

If you save and load after the second flyby camera (possibly having to quit the game first.), the game will seemingly glitch it's triggers and mission fail you if you go inside the village.

It seems it can be salvaged by simply killing enemies from the outskirts of the village.

Stinger Hunt

The script for this mission is misleading, you need to investigate every truck parked at one of the villages despite the messages implying you've already fully checked the place after taking out all the enemies inside each village.

Convoy Mission
During a late mission where you need to protect a Convoy, the Convoy timer will end instantly if you save and load during the first half.

This is not a complete list, I have also not tested quitting the game and then loading back in as that adds allegedly adds additional bugs, if you discover any game breaking issues with the game's scripts yourself when loading/quitting at several points, please tell me. (I am unsure if merely saving/loading causes the bugs or outright quitting the game is required.)

As a general rule of thumb to remember, if the mission has a scripted "Camera Pan" where it automatically moves the camera, this will break if you save and load. (Maybe you need to quit first, I'm not sure.)

I will also be re-stating the critical mission-per-mission bugs here just-incase.

Bagram Airdome

It is completely safe to save/load in every section of this mission (presumably past the opening helicopter), quitting hasn't been tested.

Pandzher Path

It is save to save/load at every section, quitting hasn't been tested.

46th Kilometer.

There are a good few camera pans early on. (When you start and after destroying the Shilka)

Saving and quitting after your allied reinforcements shows up seems to prevent the "Enemy Retreating" message popping up and prevents the mission being completed.

I'm not too sure if loading/quitting before that point is 100 percent safe but I have managed to beat the mission after resuming play after quitting during the timer but before allied reinforcements.

Prisoners.

After the camera pans when both sets of friendly reinforcements appear and are playable and you've blocked off the escape route, the game's scripts seem to semi-break, the mission can be completed but the game will trigger a fail state if you actually enter the village at some points, so you have to pick off enemies from the outskirts as much as you can then quickly clear the rest when you have to move in.

There will be no (in my experience) broken triggers to prevent you just rushing the village in the
mission if you don't save/quit at all. (I had those bugs in my first playthrough but no issue on a second playthrough where I did the entire mission in one sitting so I presume saving/loading is the culprit, this mission would need to be tested a decent bit.)

Stinger Hunt

Thankfully this mission seems to be completely safe, at least without exiting the game as there's no camera pans. (Though you need to actually get right next to the truck with the stingers to complete the level, the game will say the villages are clear but you need to find the actual stinger truck in a "clear" village to win the level.)

Oil Rig

There is a single scripted camera pan after the initial defensive section, after that, you're free to save and load.

Recruits

You have one camera pan at the very start and another after defending the hill, once you get told to fall back to the other village (With some reinforcements showing up.) near the start, it's save to save after the camera pan.

Remote Outpost

No bugs with saving/loading as far as I'm aware.

Column

The timer until your allied convoy you need to protect will instantly go to zero and they'll arrive if you save/load before the timer ends, afterwards saving/loading works with no known issues.

Height

The final (Non-Bonus) Level, there's no save/load issues here either that I'm aware of as there's no camera pans.

Secret

No Save bugs but make sure to use the fix for the "Driverless Tanks" since this mission will get much harder otherwise.

I was able to find a Russian complete walkthrough of the game, while it may have Russian text, if you're stuck or if you have a feeling that something scripted didn't trigger that was supposed to, you should be able to check with it to an extent. (Such as text boxes/events failing to trigger.)
