Don't play easy man. I would highly recmmend to play on normal. You'll feel this game much easier on Normal difficulty if you explore and get better weapons. Equip all pictos, there is no limit to it. Equip the health ones if you are dying too much.
Game opens up and completely changes in Act 2. There is this 'Reserve team' mechanic as well. I feel like the game is already too easy in main path, playing on easy would break the game.
Already I have some weapons that feel like breaking the game, one shotting enemies.
Or perhaps you guys stepped into some high level unknown territory. Do those later.
