I tried the Iron Rebellion alpha and it was kind of neat. It focuses much more on light mechs than the kind on Vox with lots of strafing and hopping around. The cockpit HUD is very pretty and I do enjoy being able to switch between weapons to cycle between them while you reload. There isn't very much to the game so far though as the only real singleplayer mode is a wave survival with one map and there are only three weapons. There is a PVP alpha too but you need to ask on Discord to get a key. One thing I think that they are sorely missing is some sort of melee option as it is very easy to get into an enemy's face in the game. The enemy AI can't jet right now but they are surprisingly good at strafing and flanking maneuvers which fits the more mobile kind of gameplay which they seem to be going for.
