Rithik BJ. You just have to play the previous levels repeatedly to earn more money and points then you buy your new armour and move ahead to the next level. Lol... I love this game. Nice game,not fair in some part,I know I would win but the game run out,the aming kina sensitive, and some of the levels kina of repetitive, let the enemy look more real instead of that red outline, my quady look real,let the other look that way, graphics so to speak. ....I guess my life runs out too quick, I know I would kill them all.......Good game still. I have been playing this game for some time; the misions, difficulties and illustrations are best case scenario. The game is extremely addictive, simple to explore and gives easy to hard challenges contingent upon what you need. Heaps of in-game content. I unequivocally recomend this game for individuals who likes sharpshooters and blowing head off!
