Likewise to the Modern Warfare series, there will be challenges that take place either daily or weekly, depending on what they are. You can find something equal to “perform 5 headshots within one minute” or possibly “stick 5 players with a plasma grenade”, Smith says:

In addition, players will receive “Commendations” for their performance in matches. If a player spends more time using a Sniper Rifle or a Battle Rifle, Commendations will reflect that in the player’s service record. Similarly, players will receive Commendations for driving vehicles.

Meta-game components in multiplayer games are usually a huge hit with fans. They certainly add that “just one more…” factor to your game time and I’ve certainly been there sitting and saying that I needed just five more kills to unlock my new weapon or to get that challenge done.

I’m very excited for Halo: Reach, which is definitely a bit of good news for me since I got burned out on Halo 3 pretty quickly. Don’t get me wrong, it’s a great multiplayer game, but I think Bungie was trying to do too much with something that was definitely not that broken.

The Halo: Reach beta will allow you to fly around on jetpacks while shooting at people on May 3, 2010.
