Call of Duty: United Fronts is a single-player mod that combines the campaigns of the original Call of Duty and United Offensive expansion pack with community created maps to form one large continuous campaign. It adds several new weapons and replaces almost all of the original weapon models. The mod requires the United Offensive expansion pack in order to play.

Content planned for future updates:
- 1939 Invasion of Poland campaign
- Operation Market Garden campaign
- More custom maps
- New and improved weapons and vehicles

Is there a way to play all missions as axis soldier??

Reply Good karma Bad karma+1 vote

Abrand Their is an axis player mod on moddb for call of duty 1 if you wanted to do that with the base game i'm not sure but maybe if you installed it over united fronts it work somewhat? as it is just a swap around i've used plenty mods etc & no conflicts after all hope that helped.

Reply Good karma Bad karma+1 vote

Thanks for your answer. I played this mod but its very buggy at United fronts. At the british campaign, the enemies are russian and the weapons makes no sound. Also get an Error very often while loading, so I can't go on at the campaign

Reply Good karma Bad karma+1 vote

Marcomix are you still interested in voice actors i did send you an audition back a year ago when we spoke about it to presumeably your email but did not hear anything back so i wasn't sure if you had got it best of luck good to see the mod is back at it.

Hi! Could it be possible for the next update to fill-in the missing textures on your arms when the FOV goes past 106?

The sounds for some weapons, like the Bren for example, are either a little scratchy or too loud, id honestly prefer some of vanilla sounds over the ones made for this mod. To be fair its only for a few weapons but all the others sound amazing overall.

Could it also be possible to implement a "no zoom" for all weapons with iron sights, as well as fixing the HUD, sniper scopes, UI and main menu Ui to be fixed at a 16:9 aspect ratio? I have a 1920x1080 screen and while the gameplay, weapons and characters themselves look good, the rest look to widened.

Look forward to the next update! Weapon selection was long due :D

Even if there are some - smaller - bugs, this mod deserves nothing less than 10/10. The new models are beautiful, the maps are like coming from an official expansion pack and the whole thing is simply professional. I hardly wait the -next - update! Excellent work!
