What is Mechwarrior Online?
Mechwarrior Online is a free-to-play, PC-based, online shooter produced by Piranha Games Interactive. MWO places you in the command seat of a heavily armed and armored walking battle machine that you pilot in team-based matches against other Mechwarriors. Your mech is very customizable and able to field a huge assortment of energy, ballistic, and missile weapons along with an array of modules and other utility items. At the end of each match you earn C-Bills, the in-game currency used to buy more items and mechs, and experience that is used to enhance the piloting abilities of your war machines. Between matches, you can customize your mech with a variety of engines, weapons, subsystem modules, and chassis enhancements until you have your chosen chassis tailored to your liking.
There are currently three game modes: Skirmish, Assault, and Conquest.
- In Skirmish, your team is pitted directly against the enemy team in a battle to the death! The team with the last mech standing wins.
- In Assault, you and your team attempt to capture the enemy team's base without losing your own, or eliminate the enemy team.
- Conquest is a traditional domination mode where you and your team are attempting to control resource nodes that generate victory points. The first team to reach 750 victory points, or that eliminates the opposing force, wins.
- Domination is about holding the center of the map
- Escort is a mode where one team escorts an AI-controlled Atlas and the opposing team has to kill it before it reaches the end.
Sounds good, where do I start?
1.) Download the client at http://www.mwomercs.com, or download it from Steam and install it.
2.) Once logged into the game, go through the Training Academy tutorials. This game has a bit of a learning curve to it and while it's not super-steep, it's definitely not just a jump-in-and-click-things-until-you-win sort of game. Be sure to watch the Weapon Grouping video as it'll do the most to help keep you alive. Chain fire is your friend, learn to use it.
2a.) Penny Arcade also did some Pilot Safety Posters and while they're humorous, they do have some good information in them.
3.) When you start the game you will have access to a number of trial mechs that rotate out for new mechs every month or so. These are non-customizable mechs, designed by PGI and the community for ease-of-entry into learning the game (except for the Stalker; that thing's a newbie death trap). Select a mech, and use the in-game Tutorial and Training Grounds to get a feel for how the game controls. Move around. Shoot your guns. Try overheating, then remember that overheating is bad.
4.) Jump into real matches! After each match you will earn some C-Bills, Mech XP, and General XP. C-Bills are the in-game currency used to buy everything except cosmetic items. At the end of each of your first twenty-five matches, you'll earn a Cadet C-bill bonus that you can save up to purchase your first mech. You'll also earn Mech XP, which is specific to the mech you earned it on and is used to buy piloting enhancements like faster torso rotation or better heat mitigation. You'll also also earn General XP that can be used on any mech, and can also be used to unlock modules and module improvements.
5.) Mech Credits (MC) are the in-game currency that you purchase with real money in order to shortcut your way to a new mechs and equipment. MC is also used to purchase premium account status and cosmetic items for your mech like new paint jobs, and items to put in your cockpit like bobblehead dolls.
6.) Need more advice? There's a solid Reddit thread here for new or returning players.
