Focus beam

The focus beam is a defense structure of the GDI in Tiberian Twilight.

Background
Essentially a large scale particle beam cannon, not unlike the one on the AW-T2 Titan, the beam fires a continuous heat-based laser, cooking enemies from the inside-out. Most effective on heavy armor.

In-game
Focus Beam is the fourth structure to unlock just right before the Falcon MLRS, 10 power points is needed to build one. It fires a constant laser beam at the target, which noticeably gets more powerful overtime, from being a lowly charged beam, it gets brighter, indicating it's continuous damage increase.

It's Nod counterpart is the Obelisk of Light that can interconnect with other obelisks instead of firing continuously.

An achievement will be obtained if the focus beam dealed continuous damage to an single enemy.
