You can add one of four things - the grenade, the medkit, the drone and the RPG. The grenade leveling up increases how much you can use it. The medkit helps heal your squad (and yourself), should you take too much damage. The drone flies in to attack and distract targets so you can catch your breath. The RPG delivers a big bang.
The best to use? The grenade and the RPG, especially when combined with exploding oil drums.
The sequel to the award winning Hellblade: Senua’s Sacrifice, Senua returns in a brutal journey of survival through the myth and torment of Viking Iceland. Intent on saving those who have fallen victim to the horrors of tyranny, Senua faces a battle of overcoming the darkness within and without.
