The CSRX-300 looks to be an anti-material sniper rifle that can pierce multiple soft walls – at least two, as shown in the trailer. It’s also got an under-barrel explosive lance which can similarly pierce soft walls, but the projectile will stop once it hits something hard, and then explode on a short delay. You can also see the operator icon, which looks a bit like an eagle’s face.
The other gadget is the Mag-NET System, which appears to magnetically stop bullets. In the trailer, we see the Mag-NET placed above a window. A gun fires from the opposite side, the bullet travels partway through to the target before it’s snatched back up by the magnet. This operator icon looks like a person meditating.
