Painkiller is a serious Serious Sam clone without Sam.By dieing,take Heaven's side on the battle with Hell's forces. First things first.The graphics are simply superb.Everything beautifly detailed & with great textures,& with the best phisic engine,Havok, Painkiller-Heaven,s got a Hitman was one of the best-looking FPS-s in it's time. As sound I know two things:music-hard rock orchestration,perfect atmosphere & never boring,& the great sound effects. Objectives:kill 'em all!About 6 weapons with primary & secondary fire. i love the stick gun,I like hanging them with sticks on walls.The ice fire ,& after it a good shotgun breaks them & makes them rest in peaces.The spinning star that can be trown too,the minigun combined with rocket launcher,plasma & sharp stars launcher are the weapons.Enamies? A lot, not funny but they didn't manage to scare me.Skeletons,wiches,etc, & the bosses.Even though it's good,the gameplay is not better than the one in Serious Sam.But Painkiller is a great game & a good start for Havok.
