Army of Two Tips

Easy defeats
Are those heavily armored enemies getting you down? Does your partner have to revive yo ua lot? Well then use this to get by them quickly and effectively.

Most bosses and heavy enemies do some terrible damage, often dropping you after a few shots. To get around this, instead equip your special weapon nad shoot them in the head. The force of the shot will knock them over onto their backs, which you can then run past an shoot easily. Are there enemies nearby? Do you have a stinger? If you answered yes to the second one, shoot them once with your stinger and watch them fly. The stinger works on bosses and Chinok helicopters aas well (although the helicopters require two stinger shots instead of one).
