Occult Scrim looks like a fun twist on Half Life: it's not quite a fully top-down shooter, but it's nearly there, with the camera floating way overhead. Your job is to blast through enemies to rack up points, which you'll spend on new weapons and items when you return to your base, an armoury.
It's still very early days for the mod, and it doesn't yet have a release date, but it looks remarkably polished. The perspective works well, and your character—a black ops assassin—automatically adjusts their aim up and down depending on where your enemies are. It looks like it plays far quicker than the base game, with lots of enemies on screen at one time.
The camera has two positions: you can bring it slightly closer to the action if you want to get extra precise. Even when it's zoomed out, the guns feel meaty and solid. I'm not sure how many of the weapons are new and how many come from the base game, but I'm impressed nonetheless.
Enemy behaviour has been tweaked from the original to make them more challenging to fight, and they'll do things like roll and strafe out of the line of fire. You'll face bosses, too, like the one below.
