Your favorite rule of combat.

[BlueMage]

The balls aren't sacred, they're a satisfying target.

 

[The Wykydtron]

When in doubt, put your entire party on healing/buff duty.

Also Rush them! It's the last thing they'll expect!

 

[Scabadus]

When you're throwing a grenade, really give it all you've got. If it goes too far, hey, at least it's in their territory now!

 

[Jedoro]

For those regarded as warriors, when engaged in combat the vanquishing of thine enemy can be the warrior's only concern. Suppress all human emotion and compassion. Kill whoever stands in thy way, whether it be Lord God or Buddha himself. This truth lies at the heart of the art of combat.

 

[exessmirror]

i have an few, but the only one i can think about is
if it's hostile put it down, once it is down make sure it is dead
and
have no emotions, your enemie doesn't have it either why shoold you

 

[Lazy Kitty]

Take every advantage you can get. Ethics are for the weak. Collateral damage doesn't matter.

 

[xdom125x]

"A fair fight is unwinnable by it's very nature.. so don't fight fair".

 

[Zeema]

Don't Get Shot- Any Game

Aim for the Face - Any Game Really

 

[Raognerrrm]

'It's not unfair, just a tactical miscalculation.'

It's just so fun to use on people who always want a fair fight.

 

[SouthpawFencer]

Try to look unimportant; they might be low on ammo.

If the enemy's in range, SO ARE YOU!

You are not Superman (marines and fighter pilots, please take note).

No battle plan survives the first contact intact.

If it's stupid but it works, it's not stupid.

 

[hedges1001]

if it bleeds we can kill it

always stealth for x1.5 damage

these are quit good,
also
dont try to be a hero, you will get shot if you do and your death will probably be in vain

 

[Sir Boss]

If your plan isn't working you aren't using enough bullets.

 

[Tax_Document]

Shank Shank Shank, do do do dodo, Shank Shank Shank, Shank their Body, Shank their Body!

 

[WolfThomas]

Mage dies first.

Okay so that's only in fantasy games. But it's a pretty darn important rule.

 

[RevRaptor]

Always always be a bigger bastard than the enemy. If they do something to you, do something worse back. Keep doing it in till they learn to stop.

It's severed us well so far, the bastards will know not to shoot at New Zealanders next time.

 

[Gregg Lonsdale]

Maximum Strength, followed by punch.

 

[Fieldy409_v1legacy]

Look tough enough and you dont have to fight.
