I'd love to see implants come back. I know you had stick for stating cash could be used but bring them in with:
No real money to acquire them, in-game resources only, and
Associate a downside as well as an upside to using them which will help create real character development. And tie to battlerank levels so players have a real reason to level up.
That's just a bit of frosting for the ps2 cake. The main ingredients have been covered by pig and others
