Guns of Icarus Alliance puts 4-player crews on steampunk airships with pilot, engineer, and gunner roles that demand tight coordination. It excels at role clarity and communication-driven victories, with PvE scenarios that make every repair and volley count. The model is fair and the learning curve is well supported by tutorials. It misses the main list because the playerbase is small and peak-time matchmaking can be spotty (SteamDB shows low hundreds). Bring a full crew or use community discords for best results. Great for niche teams craving vehicle co-op.
