Opposing Force Assault is a singleplayer mod witch uses the OP engine.Since not many people create Opposing force Mods i introduce you to Opposing Force Assault mod.Because the original OP lacked the firepower that every 1 wants i have given it to this mod,and you have always fellow soldiers on your side unlike in OP.

MISSION:1 ASSAULT

MISSION:2 REINFORCEMENTS

Since we are in the new year I decided to post an article informing everyone about the development of OP Assault.


2015 Has been a great year for the mod. I managed speed up the development a lot last year and which resulted in the release of the long awaited demo. After the demo was released I was working only on the maps shown in the demo to further improve gameplay and fixed a lot of bugs to provide smooth experience and I'm quite happy with the results :)

After my last release v1.4 of the game I've finally managed to continue working where I left off. I also decided to change the development of the mod. From now on with every "Mission" I completely map I will be releasing a version update so players can play the new content without waiting forever and also provide feedback if needed.

And this is where my last announcement comes. I released a video trailer for the upcoming version of the game which includes two new missions. Estimate release date is unknown as of this moment but it shouldn't be long.

Now for those that didn't know about v1.4 till now I recommend you download it. It contains a massive list of improvements /fixes.

Your mod description says A. Shepard is the main character, but the mod starts out just like regular Half-Life....????

I discovered that the rar file was not extracting the entire op_assault dir into my Half-Life folder. I extracted them to the dir where I put the rar file and copied them over. Sry

No, it starts with a custom map.

coverfireintro.bsp to be precise.

How did you start the mod, with the included batch file ?

I've played the demo. Looks good, but please reconsider the respawning hordes of enemies. The first wave is okay, but the second and third start to fell annoing and the next waves are just boring. I'm sure there's a way to make each of the fights feel more unique and interesting. I'll give you an example. Fighting the black ops in army camp would be much better if there was less enemies going from more sides (like blowing a hole in the wall to open new entrance or using ospreys). Other than that, I liked it and I'm looking forward to play the full mod once it's completed and fixed.
