If you’re looking for a bit of an edge in GH1, here’s a nice degenerate tactic you can try. I like this one because it gives some insight into how the game works.
The first thing you need to know is that GearHead is a clock-based system. Actions take a certain amount of time. After a character performs an action, a certain amount of time has to pass before they can perform their next action. Generally this period is the character’s Reaction Time, which is calculated based on Speed and the Initiative skill. There is one big exception to this: movement. Since it wouldn’t make sense to return control to the PC in the middle of a movement action, movement ignores Reaction Time and instead returns control to the PC when the move is completed.
To exploit this, first you need a very fast mecha, preferably loaded with overchargers. The Vadel is a good choice. Next, load it up with high-speed weapons. The more and the faster the better. In combat, start moving at full speed straight towards the enemies. Because of the movement exception described above, you will be able to attack every time the mecha moves into a new tile, regardless of your character’s Speed. If you can boost your mecha’s top speed to 300dpr or so this means an attack every two seconds.
This tactic doesn’t work in GH2, where the movement exception only occurs if movement is slower than Reaction Time.
