In Weapon of Choice DX, the Solus Operatives face an invasion by gene-combining beings from beyond the stars. The game presents this conflict through high-resolution, hand-drawn art and a bizarre alien world, with an original heavy-metal guitar soundtrack. Its premise sets up a colorful action game rather than a grounded military shooter.
Its levels are non-linear, and decisions made along the way can send a run down different branches. Each playable operative has a signature weapon with primary and alternate fire, while rescuing characters adds to the total pool of playable lives. The roster and routes give players reasons to revisit the story, which features multiple endings. Combat also has its own twist: Death Brushing can activate when danger is near, offering a chance to escape a tight spot, and the Vengeance Missile lets players retaliate for a downed operative. Wall-scaling with the automated Spiderpack adds another way to move and attack.
The store lists Weapon of Choice DX as single-player, so its branching routes, character rescues, and combat systems are designed around an individual player's campaign. Steam-specific features listed include achievements and a widescreen 16:9 format.
