Easy red 2. Discovered it looking for steam deck verified games. Kind of the feel of call of duty 2 and battlefield 1942 mixed together. It’s cheap and goes on sale for really cheap. Has some weird systems in it but it’s fun to just zone out and play through the maps. There is a ton of maps.

It’s a WW2 fps with vehicles and squads. You take over objectives on the map and either attack or defend. For whatever reason it has a full inventory system where you can loot any body. You can play different roles in the squad. As squad leader you can call in artillery if your radio Man is alive. You can also command your squad. The AI is alright, not the best but it works.
