Never had a playstation, so playing any of the exclusives meant having a friend that needed help with their co-operative campaign. Resistance was a series of games that had a variety of interesting weapons and equipment to deal with opponents, but it didn’t stop them from having the same effect on allies. My personal favourite was the hedgehog grenade, which would impale anyone in the blast radius with innumerable spikes, pinning them to the nearby environment.
However much I liked the grenade, I did not enjoy having it detonate in my face after clearing a watchtower full of enemies. True Story.
