Its always compromise when developing for VR. 2K resolution that should run at 90 FPS. Every small effect or 1 more light source is a compromise to add/remove. We are constantly improving and optimizing game. Also it looks really different in headset than on videos. Colors and visuals are not shown well in recorded video and we are optimizing and testing inside headsets.
Here few features of VRZ listed:
In VRZ you can kills using multiple techniques and variety of weapons: Shoot, cut heads with katana, Freeze enemies shutter to pieces later, burn to ashes using fuel canisters or special quest awarded weapons, shoot bow, Smash head using barbed bat or melee weapons or using shotguns + special pistols, place mines and explode, Use special bio grenades to lure enemies to dangerous places, Electrocute them using special weapons and annihilate later and more.
20+ different kinds of weapons and even crafting.
Interesting quests and rewards + sandbox mode. You can complete quests in any order or not at all.
Play finding treasure minigame with metal detector and dig out them.
Find miniscuba and go underwater (no fire weapon is working effectively there) for more quests and awards.
Several enemy types (not only zombies) and adaptive difficulty modes. Every enemy have its own behavior and attack strategy + it depends which daytime is current.
Day time changing where you should act differently to survive.
Epic boss fight.
Original music theme.
3 game modes : Story, Arcade and shooting range + minigames.
Personally for me Arisona is not good looking VR game. Very small levels, 5-6 Zombies, huge load times, average sound design and really bad VFX.
For me top 3 really good visually and overall quality examples in VR are: Robo Recall, Unspoken and The Climb.
