Kalran: Tales of the four nations/Prototypes workshop

The Prototypes workshop is where the UCA constructs experimental ground vehicles to support the current UCAAF arsenal.

Compared to the Armor depot is these prototypes are a lot more powerful and all the units are unlocked instantly, with tier upgrades instead upgrading the facilities protocols and advance upgrade in the lab. On the other hand their are significantly more expensive, and most of them are severely fragile for their cost. Though fortunately their mechanics are sturdy enough to be repaired, meaning that the husk they leave behind can be revived with Sappers.

Unlike the other UCAAF vehicles they are not able to coordinate attack with each other. But instead they can buff surrounding infantry and vehicles from the Armor depot, acting as a force multiplier.

Due to UCA engineering and safety all vehicle crews can evacuate their vehicles to either repair it or capture territory. But unfortunately, unlike the ones from the depot, the crew can't escape if its about to blow, meaning that when the vehicles blows up while the crew is inside they will die with it, leaving only the husk to reclaim.
