Heavy Gear [consoles, PC, mobile]
The last Heavy Gear game I recall was made by Activision for the PC in 1999, after losing the BattleTech license.
Today, the newly formed Stompy Bot has announced they will bring Heavy Gear back into the digital world. Nothing much is known about the game as no screenshots or teasers have been released with this announcement.
In contrast with the massive 'Mechs found in MechWarrior/BattleTech, the Gears take direct inspiration from Armored Troops VOTOMS so game mechanics could be more similar to Hawken than to MechWarrior.
I've never been a big fun of Heavy Gear as I am of BattleTech, but more mechas around, the better.
