It’s well past midnight. The outpost is silent. Nothing moves. Suddenly, a monster de-cloaks right in front of you. You look around frantically for some sort of weapon but you only have two melee ones at hand: a Half-Life-like Crowbar and a BioShock-type Wrench. Which one should you choose? The Crowbar helped Gordon Freeman crack alien-infected skulls of scientists in the dozens (and some supply crate, from time to time). The Wrench deals more damage, but do you think you can deliver it without plasmids and EVE shots? Best be quick and make your choice, the monster already has five weapons targeting you: teeth, claws, acid spit, swearing and a photo of its girlfriend.
