#1. Reload often, and use your backup gun instead of reloading when in combat.
Pistols and shotguns are faster to switch to while fighting than reloading,
and honestly you don't lose a lot in firepower by switching, just maybe a
little less speed of firing.
#2. Cover cover cover. This isn't a cover-based game with a stick-to-the-wall
mechanic, but you still need to use anything you can to hide behind and peek
around the corner to fire, or use anything else in your inventory to scatter
enemies. Lastly, many guns can shoot through surfaces, so use caution when
hiding behind cardboard boxes.
#3. Sprinting almost makes you un-hittable, but of course you can't fire
during. If you're position is compromised and enemies are surrounding you, or
a frag lands near you, just sprint away. If you are caught in the open and
under fire, just sprint away to cover. You'd be suprised how often you can
save your a** this way.
#4. Preset enemies are more common than the infinite streams this series is
notorious for. But more importantly, you need to realize that this game
doesn't have "gates" that are opened by killing X number of enemies, usually
the missions progress just by you reaching an area or using something. Rarely
is it your top priority to kill everyone firing at you. And as we said,
sprinting makes you hard to hit, so kill a few enemies and sprinting to the
path is best in some instances.
#5. Don't waste your tools, but don't forget you have them. Yeah, requires some
advanced knowledge to know when in a level to use certain things like smoke
grenades, but so long as you don't blow them all in one fight, probably okay to
use them when you want to.
#6. Stick to your allies. Less of them will keep getting replaced, but they
are still valuable to not only try to protect, they do very well to help
you kill enemies.
#7. Frag often, frag hard. Your grenades should be used often because you'll
find more all over. Use them when you see clusters of enemies, or you are
pinned down.
#8. Cook your frags, meaning you hold the toss button for about one-two seconds
before you toss it. This reduces the chance the enemies can toss it back.
#9. Rarely ever swap guns that you are given, especially on the "sniper"
missions, but I try my best to tell you when to swap out.
#10. Make sure enemies are dead, a wounded enemy can fire pistol rounds at you
if you don't kill them.
