I didn't even notice they tried to take on Steam.

The creator has stated once the refactor goes live and pull requests are repoend, the CLA will be removed. Time will tell if they stick to their word.

Half-Life 2 and the Bungie era Halo games. I normally replay them all at least once a year. Steam workshop support for both of them has also been great.

I've seen it talked about a few times but here's an instance of it from early on (sorry for the reddit link): https://old.reddit.com/r/FluxerApp/comments/1r8724q/heads_up_fluxer_has_a_big_red_flag_it_requires/

Essentially, he had plans to possibly offer commercial versions of Fluxer, but plans changed after it took off in popularity 4 months ago.

Agreed. The second one is one of my favorite custom campaigns for any game. Very well done I thought.

Looks like it does support 4 player co-op, at least according to the PC Gaming Wiki. I'll have to convince my friends to try it sometime. I love SS2 but never tried it in co-op.

That's a great suggestion. I actually already have ADACA but haven't played it much. Something else must have taken my attention away from it at the time.

Thanks for the reminder, though. I'll need to get back to it!
