War Games refer to a collection of game types in Halo 4 in which you play competitively against other human players. These battles are training simulations performed by Spartan IVs onboard the infinity, which they use to improve their abilities for Spartan Ops. There are no computer controlled enemies in War Games; every single ally and enemy is a real human player.
War Games offers an interesting dynamic to Halo 4 quite different from either the Campaign or Spartan Ops. Because you are playing against real players, you get an opportunity to fight enemies much more intelligent than those in the Campaign or Spartan Ops. Therefore, some of the strategies that I provide for the Campaign do not work nearly as well in War Games. There is no single “best” strategy, so experiment with many different tactics and choose one that best fits your strengths and play style.
In War Games and Spartan Ops, you receive experience after completing each game. This experience is used to level up your Spartan IV character. As you level up, you unlock new equipment (such as weapons, armor abilities, and perks) and new armor. Each level requires more experience to unlock, so you will level up quickly at first and slowly later on. After you reach level 20, you will have unlocked all equipment, and any levels past that will have little effect on your gameplay.
There are 3 ways to gain experience. The primary way is to complete games in either War Games or Spartan Ops. After each game, you will be rewarded a fixed completion bonus and a much smaller bonus based on your success during that game. In general, you will receive around 2500 experience from shorter games (slayer, oddball, etc.) and 3000 experience from longer games (Spartan Ops, Big Team Battle, CTF). The second way to gain experience is by completing challenges. There are an assortment of War Games, Campaign, and Spartan Ops challenges that you can complete to gain extra experience, with rewards ranging from 1000 to 20,000 experience depending on the difficulty of the challenge. Challenges come in many variations, such as killing a certain number of enemies in a certain way, winning a certain number of games, or completing a certain campaign mission on a certain difficulty. New Challenges are added periodically. Finally, you can gain experience by completing commendations. Commendations are similar to challenges, but they have no time limit and new ones are never added. There is a large assortment of over 100 commendations, each with between 5 to 7 stages of completion. Every time you complete a new stage of a commendation, you receive a certain amount of experience. You can also gain new armor and weapon skins by completing the highest stage of certain commendations.
After you reach level 50, you can choose from 8 different Spartan specializations. Each specialization requires 10 levels to complete, and you unlock new armor with each level. After completing the final level of a specialization, you unlock a new perk. While these new perks only have a minor effect on gameplay, they do offer useful bonuses such as more experience per game, faster assassinations, or longer overheat times on vehicles. Once you complete all 8 specializations and reach level 130, you have completed the leveling progression and will no longer level up.
Throughout the leveling process, you will unlock numerous pieces of armor, all of which can be accessed from the “back” menu. This allows you to customize the way your Spartan IV looks in both Spartan Ops and War Games, but has absolutely no effect on gameplay. You unlock new armor by reaching new levels, completing commendations, and completing armor-specific challenges.
Unlike in the previous Halo games, you can create your own loadout in Halo 4. Each loadout consists of a primary weapon, a secondary weapon, an armor ability, a grenade type, and two perks. You can have 5 different loadouts at one time, allowing you to develop different combinations for each situation. These 5 loadouts are used in both Spartan Ops and War Games, so I suggest that set allocate 2 loadouts for Spartan Ops and 3 for War Games.
Below, I discuss which equipment to use in your War Games loadouts. However, these are only my opinions; you should develop a loadout that fits your play style the best.
Primary Weapon: I highly suggest that you use a headshot weapon as your primary weapon, as headshot weapons have a much longer range and kill enemies faster than any of the assault weapons. I suggest that you use either the DMR, Battle Rifle, or Light Rifle. Of these Options, the DMR is the most accurate, the Battle Rifle deals the most damage when not zoomed in, and the Light Rifle deals the most damage when zoomed in.
