Listen up son!

BT Mission 1 level 2

Version 200

Okay, so let me start with a big apology for all those who have been waiting!
We are sorry to disappoint you a little. We where hoping to provide more maps from BT and have a earlier release date.
How ever, your waiting is being greatly rewarded with the most advanced update this Coop mod has seen since the start of its development!
Smithy has put all his love (and probably some of his British Humor) into the Mod, the result is:
Smarter AI, a Complete Weapons Inventory and a few technical important updates.

New Major Features

- Dedicated Server support
- Full Inventory in Coop
- Smarter AI - AI Handler
- Last Man Standing Mode
- 3 Levels from BT are Coop ready
- A gametype handler for using incompatible commands in multiplayer
- Updated Score Board with Mission Infos
- Call Vote option for the Missions
- Almost 300 Changes in total.

Motivation and Time

As you might have noticed our development rate has dropped quite a bit, despite the new blood.
Smithy has worked out the finer and more advanced issues the Mod had and will continue to do so.
As you might have guessed the enthusiasm for the Mod has dropped a bit with the really heavy workload of the BT scripts and life catching up, but we are still trying to get it done.

Future Development

We do not have the manpower to progress at that quality with a rate that would be healthy to the Mod.
Instead we have decided to provide updates more frequently and fix issues once they are reported.
This way we have more maps converted and playable in a much shorter amount of time, how ever you will expiriance a drop in quality until the reported bugs are fixed.
Despite this quality drop, this Mod will continue to be the most stable and best playable Coop Mod for MOHAA and its addons.

Custom Maps/Mods

Want your map in the Coop Mod ? Contact us!
We are offering to convert map-scripts from singleplayer to Coop.
We like to see custom Maps and Mods in our Coop and we like to support them.
For the moment we will concentrate on less complex fairly simple maps with little scripting and no or very easy modifications to the actual game.
Chrissstrahl is open to talk in discord or Teamspeak about that.


We will change the Public Stable 1.51 server to the released 2.00 Version soon.
The public development server will have the latest version (you might not be always compatible). / / connect

Custom FOV

We have 2 offical Coop Mod servers with FOV unlocked, so you can set your own fov that fits your screen resolution. Use this command into your console to set your fov (while on the server): setu cam_fov 90
This FOV thing might not work else where at this point of time.


You will continue to run into bugs.
Take a screenshot and retain as much useful information of the bug so we can reproduce it.
We will fix all reported bugs that break the game quickly, but only if we know how to reproduce them.bugs

I can not seem to find servers for coop at all. Is there a chance you can add bots for this mod soon?

This mod does not support dedicated server yet.
We do not have the manpower to provide that any time soon.
I think that bot-support is very unlikely to come.

Just to quickly ask, how did you create the medic bot for example in mission 5 level 1|b (The one with the tank crew trying to infiltrate city hall to steal king tiger tank). I have been trying to figure out how the MOHAA creators made the scripting for the medic bot and don't know where to look. So if you have the time please just explain to me how you created the medic bot. Just answer in the reply plz

Look into global/ai.scr (located in pak0.pk3) and find label 'medichunt' to understand how the original creators implemented it.

I have a question/request.

When comparing this coop mod to the older other coop mod, the other coop mod had three "difficulty setting": easy,normal, and hard. The harder the setting the more AI's there would be on a level.

However, although this coop mod is a great improvement, It is not as much of a challenge. Although there are five difficulty settings: easy,normal, hard, very hard, and "just die", none of the settings change the number of AI's present on any level.

I was wondering if I could beg y'all to add more AI's to each level per difficulty setting in y'all's next update to please make the coop gameplay as challenging as it was in that older other coop mod?

Other than difficulty in terms of the numbers of AI's per difficulty setting I give the mod a 10/10 rating! :)

Thank You Gentlemen

From discord chat:

Thanks for your feedback,
we are still working on the Mod, we will start BT part soon.
And we focus on high priority things first, like getting it to work in general.
We have plans to add add more AI and make it more difficult later on.

But we want first to provide a stable and well working mod that can then be expanded in terms of features.
Criminal was already pointing that out to me that it is to easy and we need the difficulty to work, but workflow wise it is better for us to do this at a later stage.

So this is on me that the difficulty stuff is incomplete

Can you tell us which maps are really bad ?
Then we could adjust them with the next relase a bit.

Yes Sir, I want to help as much as I can so therefore I plan to play through each level one by one and then report back with an "AI difficulty report" and "bug/glitch report" for each.

Should I post my findings here on moddb or on the discord feedback section?

And also, Is it all right with y'all if in my "report" I make comparisons between the "other coop mod" vs. this hazardcoop version, because this mod seems like an upgrade of that other coop mod and there are areas where the hazardcoop version has make improvements but has take a fews negative steps back as well.

Thanks, please report to Discord Chat, it is more suited for that.

No, go ahead, make comparisons, the HZM Coop Mod has been done from the scratch, so I am curious of what is the same and what is better or worse.
