— JANINE'S BOTS - SPECS AND OVERVIEW - CHIANG "ARCBOT" MODEL 2
The Model 5 moves extremely slowly, but can shoot bolts of electricity that cause significant damage and drains bioelectric energy. With 400 HP, they are the second toughest bot in the game after the Page Delta-2 Peacebringer. The Model 5 only has 100 EMP HP, however, and can be taken out with a single EMP grenade.
