Ben G: "You have a big arsenal of weapons in Serious Sam HD, starting with a knife and revolver, and later on going to some big guns such as the cannon and the almighty Minigun, which can tear through hordes of enemies in seconds. The ammo pickup system works well, although I didn't find health pick ups very satisfying, especially armour. In some areas, pickups would add about an extra +1 health to your amour, which unless in bizarre circumstances, wouldn't be beneficial in any way. I personally think this game could take a few hints from Call of Duty, armour can stay, but health should recharge to a set limit overtime. It would certainly add a degree of difficulty to the game."
