You all know Willbachbakal a cool guy. He made what upgraded leadhead splicers would be like. Well heres my take on what some new leadhead splicers should be. The old ones will still be in the game, But these are new ones. Research rewards will be the same as Willbachbakal research rewards.
Crossbow leadheads: They use a crossbow to attack you Go figures. Upgrade: They use the Piercing Shot upgrade and use insect swarm
Sniper leadheads: They use a scoped elephant gun. Upgrade: They also gain the Extended Clip upgrade and winter blast.
Grenade Launcher leadhead: They use a grenade launcher. Who Knew! Upgrade: Homing Grenades and Incinerate!
Those are my new leadheads.
