edit: updated a review to give more info a bit
This is one of the most 'solid' EA release I have ever played. If you are looking for a solid Mechwarrior-like combat, this game can give you that. There are things that need polishing. However, the downside is that you can hardly find people to play with due to the soft launch. Devs are fixing things and will do a proper launch soon.
To top it off, it is a Team vs Team, heavy mech combat. You cannot skate around super fast and do crazy manuever like Armored Cored's mech. Your mech is basically a tank with legs, so no fancy movements.
You build your mech from several chasis(will be adding in the future updates), put on the weapons and equipments. To balance the fight smaller chasis is faster, but less armor, and carry lighter equipments. Bigger chasis is slower, but tougher, more armomr, heavier weapons, however, loadout comes down to the battle points, you cannot just put anything in there, it is limited by battle points for each mech, and different mech will have different points.
The combat itself is fun, especially with another player. There is AI support for both single and multiplayer match, but it is not that smart, however, they do there jobs well, especially when they are with players. Combat will be tactical to certain points that you need to manage your weapons, you can fire all weapons at once or as a selective group, which can be set in the hangar. Weapons have its effective range, some can easily overload your system, and some weapons' projectile do travel the distance, so they can be dodged.
There may be claims that it takes too long to take down a mech, which is not true if you know what you are doing. Your mech (as of the current build) has 3 parts, torso, and 2 legs, and around 7-8 additional parts depending on your loadout. These parts have their own HP, so if you just shoot at every part, not just particular part. It will take a while to take down a mech. Mechs can be take-down by destroying their bodies, or both of their legs.
Nice and Solid Gameplay despite the EA release, but the Soft Launch is killing it slowly.
