Pros
Pro Fluid movement
Unlike a lot of Vive games that rely on teleportation, Onward has fluid locomotion using the gamepad. This makes the gameplay a lot more realistic, especially given it's a multiplayer military sim.
Pro Very realistic military sim
Everything from the sounds, how you reload and fire your weapon to the graphic for the map all come together to create a highly realistic and immersive military simulation. It's like ARMA in VR.
Pro Great communication
The built-in mic on the Vive makes team communication a key component of this game. It's also very realistic as it's just how a military squad would communicate over radio.
Pro Very fun
Pro Control is super intuitive
Being that the users view is controllable with their head, which frees up both hands to control the dual wielded pistols makes for a very intuitive and natural way to play a first person shooter. No longer do you have to have your guns in sight in order to shoot in the direction that you would like.
Cons
Con Very little depth
There is not much to do in the game other than shoot robots, it give a Space Invaders type feel, but in VR. This may change in the future since this is an early access game, but currently the game is pretty shallow.
