+            production: Player's hacknet production multiplier,
+            purchaseCost: Player's hacknet purchase cost multiplier,
+            ramCost: Player's hacknet ram cost multiplier,
+            coreCost: Player's hacknet core cost multiplier,
+            levelCost: Player's hacknet level cost multiplier
+        }
+
+    Example of how this can be used::
+
+        mults = getHacknetMultipliers();
+        print(mults.production);
+        print(mults.purchaseCost);
