Mechanical Frame

Mechanical Frame is a Mecha upgrade that increases walking speed. Because flight mode speed is fixed at 1.5 times walking speed, improving Mechanical Frame also increases flight speed. It does not affect cruise mode speed.

This upgrade is mainly useful for short-distance movement. For long-distance travel, it is much faster to switch to cruise mode, which is unlocked through Drive Engine research and reaches 100 m/s or more. When factory expansion starts covering a wider area at once, or when frequent medium-range movement makes switching into cruise mode feel cumbersome, investing in Mechanical Frame becomes worthwhile.

The upgrade levels raise Mecha movement speed as follows:

• Initial: 6 m/s
• Lv. 1: +1 m/s, 7 m/s total
• Lv. 2: +1 m/s, 8 m/s total
• Lv. 3: +1 m/s, 9 m/s total
• Lv. 4: +1 m/s, 10 m/s total
• Lv. 5: +1 m/s, 11 m/s total
• Lv. 6: +1 m/s, 12 m/s total
• Lv. 7: +2 m/s, 14 m/s total
• Lv. 8: +2 m/s, 16 m/s total

In practice, Mechanical Frame is most noticeable early and mid-game, when the player is still doing a lot of on-foot travel inside a growing production area. Later on, once cruise mode becomes the default for long trips, its value shifts toward making local movement and frequent repositioning smoother.
