Hello. This is a guide to help out any new Halo 4 players
First off, know that Halo 4 is the first FPG (first person grenadier) in the Halo series. Get used to switching your primary trigger finger from right to left.
Now, you have 3 primary weapons. The frag grenade, thr plasma grenade and the pulse grenade. First, decide which tactical package you want, resupply, which lets you pick up more grenades, or grenadier, which increases your grenade carrying capacity. And be sure to use the explosives support upgrade, for more damage with grenades.
Now, let's run through the primary weapons
1. Frag grenade. Oh teh noez, there's an enemy coming round the corner?! Time to switch to your frag and spam them round that corner! Don't let them come round the corner and outplay you with a gun (more on these later) instead, show them no mercy with your frags. Another situation where you can use frags is when you see a battle at the other end of a corridor. Spam all your frags in there and blow the enemy to smithereens!
2. Plasma grenade. Cornered? Been outplayed with a gun? Save yourself with plasma grenades! When your shields are down, and someone more skilled than you is about to kill you, spam all your plasma in their direction. Hopefully you'll get a lucky stick, which is a guaranteed kill! Also, try using active camo and camp round corners. Then stick any sunsuspecting bypassers! Also, if your team mates decide to use guns, stick behind them and support them by spamming lots of stickies!
3. What's this? You're out of frags and stickies, and have to use a GUN? Oh no! There's a much higher chance of getting outplayed when you're using something you're inexperienced with! Well, this is when you use the pulse grenade! Wait around the corner, and spam pulse grenades at the enemies! This will take down their shields, allowing you to finish them off before they outplay you!
Now, you have these secondary weapons called guns. These are used for firing projectiles at the enemy. Since they require a bit of aiming and are harder to use than grenades, only use guns as a last resort. Use them for finishing off survivors of your grenade spam.
Happy grenading!
