A great F2P but needs some work.
Other than the whole issue of free v. play the game is quite nice. The graphics are solid, controls are intuitive, and a variety of gametypes are available to play. The leveling system is extremely problematic and makes it difficult to lower level players to defeat higher level ones. The weapons have alot of variety and attachments that allows almost millions of possible creations. Hardsuits (mechs) provide a nice mix into the game but can be difficult to destroy unless you know how. Armor is divided into three basic types (heavy, medium, and light) but it is hard to tell the difference between the three except for some very small numbers on the info screen.
After playing several hours I've noticed very few bugs or major glitches in the game and patches are consistently coming out. New weapons, mods, and heroes are constantly being added meaning the customization options are ever expanding.
All in all the foundation of a truly great game is there but it is hidden by a biased leveling system and "free" to play.
