No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $633.2K — a different platform, not this one.

BattleZone 98 Redux

One of the greatest sci-fi strategy games of all time returns with remastered visuals and online multiplayer. Enter an alternate vision of the 1960s where the “space race” is nothing more than a cover for an interplanetary war between the US and Soviet Russia over mysterious alien bio-metal. Take command of an army of sleek heavy assault tanks, strike cruisers, APCs and more, and wreak havoc with super-heated projectiles in your mission to blast your enemy from the face of the Moon, Mars, Venus, Titan, Io and Europa. Scavenge the battlefields for crucial bio-metal, deploy powerful defenses, construct advanced facilities and escalate each battle to an epic confrontation. Revolutionary, revitalised and remastered, Battlezone 98 Redux’s blend of thrilling first person action and tense RTS gameplay is as essential now as it ever was. Two Explosive Campaigns - Play as American or Soviet forces in two separate singleplayer campaigns, with 29 missions across 7 different planetary environments. Sleek Remastered Visuals - Play Battlezone 98 as it should have been, in HD with completely remodelled vehicles and buildings, enhanced lighting and shadows, improved particle effects, upgraded animations, upscaled terrain, and more. Online Multiplayer for 2-8 players - Experience the classic rush of "Deathmatch", or test your skills in a pulse-pounding battle of wits in "Strategy" mode.
