It *is* better than Redemption and especially Ressurrection, but considering those are two of the most ♥♥♥♥ poor attempts at making a videogame I've ever played that's like saying that Desert Gunner is better than Air Control. It's functional, yes, but that doesn't really make it good.
It's got the same "kill a million dudes, another six feet of the level opens, then kill a million more dudes" that the last two had, but the main difference here is that that "zillion" is down from the "trillion" that Redemption had. Redemption was unplayable because you simply did not have the space, health, or ammo to kill all the enemies in each level. This one you actually do, and i was able to play through in insomnia difficulty without ragequitting like in Redemption, where going through without cheating was virtually impossible due to bad game design.
Which is this game's problem, the design. It's not BAD, like in Redemption. It's not completely broken like in Redemption where it's unplayable. But it's not quirky like Overdose and it's not excellent like Black and BooH or H&D, it's just kinda... there.
There isn't much to recommend here. It's functional. It's about six hours of painkilling entertainment. But it's not really any good entertainment. No new weapons, enemies. There are five levels: A church (seriously, enough with the dang churches. Every painkiller's had a church level and it's just never that interesting), a highway (the sole interesting map), a graveyard (again, yes, for the fifth game in a row), a warehouse (yes, again, another damn warehouse), and a mayan temple that's actually kinda cool, and one other level so generic I forgot about it already.
So all in all, if you're like me and on a holy quest to play every painkiller game ever made, get it because it is in fact a painkiller game.
If you just want to spend ten bucks on a good game, well... it isn't. It's not bad, but it sure isn't good.
