So far, in beta, the game is looking very solid. You start out, ranked Trainee, with weak guns, and weak power. You can't buy any add-ons, gear, weapons, equipment, etc. It is all unlocked when you get out of the Trainee stage. Once you rank up, which would be PVT, you unlock the items in the Store, allowing you to have a free range of customization.
The gear is looking really nice. The helmets are sweet looking, there are multiple suits you can wear, there's a solid gun choice, there are a lot of different types of scopes and launchers you can add on to your gun. Everything is more "electrified" in Repulse.
You will see a huge difference in how you perform once you get to the rank of PVT and you are free to customize your soldier. You can kill people faster and you can stay alive for a longer period of time, depending on what suit you purchase. There are suits with high defense/low speed, and there are some with low defense/high speed. It's whatever you prefer.
I have really been enjoying the game so far. My in-game name is BethelsBoy so hit me up sometime and get a fight going sometime with me!
