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.

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.

I didn't post it in the HL mods section because it's an OF mod. Well it doesn't really require OF to run it's just that it's a mod based from it.

I could move it but is it a good idea?

Yes, it is. There are many mods in HL section that are based on OF.
It is just a suggestion... You can see that people rarely write posts here in OF...

the issues are just some minor one that i have with the story like why the black ops are coming to the delta complex , sure , it makes the story interesting but well , kinda nonsense cuz your team is supposed to find out what happens there , not like black mesa where you supposed to cover up the incident but fail, not really the game , also , sorry that i bother you but i am stuck at the conference room after beating the black ops , may i ask what am i supposed to do next

Before you entered the conference room did you wait for the 3 soldiers to enter before the door was sealed? If you did then one of the soldiers will say he heard something and another elevator door will be open.

Yes , there is 3 dudes , the ski mask dude , the engineer and the black berret , and i think there is one dude whose is green berret that is left behind because the scientist closed the door , and then i activate the radio so we defeated the black ops at the elevator and stuffs , then do i have to interact with anything because i just screw around like an hour in that room and nothing happen

The Green Berret is the most important one. You should have waited for him to enter before the doors closed.

To proceed now you have to cheat your way. Noclip in to the third elevator that didn't open and proceed from there.
