Embellem...Hal's Sword is a crossover item from Halo. It's the Halo Energy Sword. You get the Master Chief armour and an assault rifle from the same chest.

As for transforming...honestly, I'd keep it in form and make it a railgun. It's already got the gap between the two blades facilitating the railgun's shooting mechanism. No need to transform at all.
