What made INS Source really good is its lethality. every single bullet shot is extremely threatening and dangerous. Now Sandstorm is basically a CoD clone where everyone is running around frantically because its takes too long to die.
The choice of AP ammo also made the player make very hard decisions when customizing.
Should I remove AP for a 7x scope? Should i take AP, but without an extended magazine? Should i take AP, but no grenades? Remove my heavy armor for AP ammo?...etc.
It made the player think about sacrificing power for more strategic options. Now you can basically add a thousand attachments and customization options, and you'd still have points to spare.
This game is losing its way.
