The Seeker Gun is a weapon manufactured by Megacorp in Going Commando. It is a wrist-mounted cannon which fires slow seeker missiles, which lock on to the first target to come in range of it, followed by slamming into it at high speed.
The Seeker Gun could be purchased from a Megacorp vendor upon reaching Barlow for 5,000 bolts, and could be upgraded to the HK22 Gun with use, which fires three seeker missiles instead of one. In challenge mode, it could be upgraded to the Mega HK22 Gun for 200,000 bolts from any Megacorp vendor.
The Seeker Gun is a purple and grey wrist-mounted weapon. It is fairly short, featuring a large muzzle from which the missiles are launched, two energy highlights on its sides, and two purple and grey claws below. The seeker missiles are purple with two vertical claws that slowly hover forward before targeting an enemy.
The HK22 Gun has a similar appearance. It instead is orange and silver, with shorter claws, and one claw on top of the weapon, and more glowing highlights.
The Seeker Gun is a long range weapon, with moderate to high damage, but relatively low ammunition. Its low price makes it an excellent purchase, and it serves as a powerful weapon against both long distance targets and at point-blank range. While useful against almost any enemy, it is rather cost-inefficient against very weak enemies as the explosions have a very low blast radius, and it lacks the ammunition to keep up with large numbers. It is also impractical to use against groups, as although the Seeker Gun can be fired rapidly, the missiles will often lock onto the same target and thus hit it multiple times, which is wasteful if only one would have been enough. The Seeker Gun is quickly outclassed by the more powerful Minirocket Tube, which is much faster, deals more damage and has a greater blast radius.
The HK22 Gun's ammunition may be reduced, but as it fires three missiles rather than one, it is more powerful. Much like the Seeker Gun, however, it does not hold up against the mid to late game enemies. The weapon has two weapon modifications: the Shock Mod and the Lock On Mod. The Lock On Mod causes the missiles to open and launch at enemies immediately upon firing, nullifying a previous risk of a missile hitting the wrong enemy. The Shock Mod increases the damage of the weapon and slightly alleviates its issue with large mobs of enemies, though the player should prioritize mods for other weapons as the Seeker Gun and HK22 become outclassed later in the game.
