Dino D-Day was originally a Half-Life 2 mod that was later released as a stand alone Multiplayer FPS game on Steam. The game is set in World War II with a twist: The Nazi's have somehow created Dinosaurs that they use to fight the war. Gameplay is similar to Team Fortress 2.
The Walther P38 is the sidearm for Camille Brun, the Allied Medic. In-game the name 'Walther' is dropped and it is simply referred to as the 'P38'. Oddly, despite being a weapon heavily used by the Germans during World War II, this weapon is used by an Allied character.
Capt. Jack Hardgrave can carry an M1 Garand as his primary weapon. As with most video game incarnations of this weapon, you can only reload when the weapon's current clip runs dry.
Hardgrave can also carry a M1 Carbine as the primary weapon if the player chooses so. The weapon carries more ammo than the Garand and can reload mid-magazine, but deals less damage to enemy players.
The Karabiner 98k appears as the Mauser 98k. It is the primary weapon of both Hptm. Kurt Streicher and Hissman. Hissman, being the Axis sniper class, has a scoped variant. Additionally, unlike Streicher, Hissman loads his weapon one bullet at a time, probably due to the scope. Streicher uses a 5-shot stripper clip.
The Browning M1919A4 appears as the .30 Cal MG, and is the weapon attached to the back of the cyber-Protoceratops, Trigger. The weapon cannot be reloaded, but can overheat, and if it fully overheats, the weapon must cool down completely before being used again. Once ammo is dry, Trigger must find ammo on the ground or resupply back at the base.
The Winchester Model 1912 "Trench Gun" appears as the Trench Gun. It has the slowest reload of all the weapons players can use. It is the primary weapon for Blithe-Crossley.
Frank's sidearm is a weapon called the Flechette Gun. It is a single-shot handgun that fires shotgun shells and appears to be a heavily modified double-barreled shotgun of sorts. The weapon has zip ties around it, which is anachronistic as they weren't invented until 1958 and the game takes place around 1944.
The Model 24 Stielhandgranate, with a fragmentation sleeve, appears as the Stick Grenade, and is used by both Hissman and Streicher. Von Graff uses a healing pack in the grenade's place. Similarly, Brun also does not carry an explosive, a common trait between the medics. Model 24s are also used by the Axis Compy class, who wears one on their back. Compies act as suicide bombers.
Vike can dispense Jack Rabbits to distract Velociraptors and Microraptors. She can kill them while they're eating and as the other player looks on in shock and anger as his dino is gunned down in front of him while eating the rabbit.
Fists
All allied characters minus Trigger can use their Fists as a backup weapon.
Knife
German human classes use knives as a backup weapon.
