Hello developers.
You could put these weapons in and the game would be "perfect"
Important weapons: sword like a katana (no swords in the game), grenade launchers (ammo types like explosive, acid, incendiary and freezing), flamethrowers, Claymore mines (a fancy mine, the others in the game are homemade), minigun (next from M60).
Majorities are achieved in the later stages of the game and some in very dangerous military complexes.
Other weapons: RPG-7 rocket launcher (this famous weapon as it is not in the game), barrett M82 precision rifle (with its .50 caliber), missile launchers with guided missiles.
Important Traps: Flamethrower Turret, Gatling Turret (next to smg Turret), Electrified Fence.
A modification for the AK-47 and the tactical assault rifle, an explosive but shorter range grenade launcher (Rambo).
With these weapons and those that come in alpha 20 the game is completed with weapons
