I used to play, back in 2018–2019, an adventure and action game on Android. It was kind of like a pixel Rambo game, where you controlled mercenaries and went through maps killing bandits. What I remember well is that it had crazy deaths, like rocks falling on top of you or falling onto spikes, and there was pixelated blood. I remember you could throw grenades, use weapons just like in Broforce (Broforce), maybe it’s my imagination but I remember it being a bit more realistic than that game, with a lighter background. You could climb ropes, it started in a truck, you rescued people who were trapped, blew everything up, pixelated blood, rocks, grenades, etc.
Would it be Gunslugs 3?
