Here's what makes HL2M suck
- The gravity gun requires no skill to use
- All weapons except explosives and objects fired with gravity gun does too low damage
- No longjump module, making the game too slow
- No gaussgun, making the game too slow
- Annoying sprint-system; it is exhausted after about five seconds
- Last and worst of all, the Rocket Launcher; it can be wielded by anyone and the one who has it can easily beat everyone else

HL1M is a great better game, and I'm disappointed that HL2M became such a failure.
