Out of money , tired of working hard to increase your level, frustrated.......Well you just bumped into the right topic.
There are many methods to stack up XP and points. Some require little bit skill while some require virtually nothing....Here I'll be explaining you a method which even newbies can do.
Well here's the trick.
Search for a Skygarden Team deathmatch game having 4/8 players. Now join the desired game. Then press TAB and check which player has the GOLDEN GUN. If he's on your team then no threat but if he's on other team then try to make him kiss the earth using any rapid firing weapon. After you've done this check your health. If its above 50 then you're good to go , if not then use a health bot. Now wait near the golden gun SPAWN PLACE at the MIDDLE PLATFORM. When it spawns , snatch it and make it to the enemy base. While you are waiting be careful to watch your back for any incoming hostiles. After making it to the enemy base kill all of the enemies using the golden gun (USE LITTLE AMMO FOR THIS STEP). Now when the sector is clear wait behind the cubes at the end of the enemy base (CROUCHING IS A GOOD IDEA) and wait for the players to respawn. When they respawn wait for 3 seconds then rush at them using golden gun. When all of them are killed go back to your hiding place and wait again. When your ammo is below 10 then go to the middle platform and refill. Then head back to enemy base and kill them. By doing so you can easily stack up 30 kills at the end of a 15 minutes game even if you are a newbie of lvl5.
Hope this trick was helpful. I'll post other methods shortly.
