The hacks include ESP (Extra Sensory Perception) too see enemies clearly without a hassle. The hack also includes Bullet Tracing, bullet tracing allows you to see where the bullet is coming from (kinda like starwars lasers). There is also another modification that allows you to remove smoke from smoke grenades and explosions (so they don't obstruct your view).
The hacks currently being worked on are God Mode, and Wall hacking.
Wall hacking and walking through walls has just been confirmed, it's in beta testing though.
