Xeno Assault 2

Hint: Super Beam:
Use the Super Beam only when needed to keep it charged. Use the Super Beam to take out large groups of enemies at once.

Hint: Star Beam 2000:
The Star Beam 2000 is only available in the full version of the game. It passes through all enemies in a straight line, damaging them equally. Try to hit groups that extend far upwards and shoot it in short bursts.

Hint: Photon Wave Laser:
The Photon Wave Laser is only available in the full version of the game. It travels through enemies and does very high damage. However it has a very limited number of shots. Use it carefully.

Hint: Avoiding damage:
Keep moving to lessen the concentration of enemy shots at one location, making them easier to dodge.

Hint: Invulnerability:
After getting the Invulnerability power-up, ram your enemies to destroy them quickly.

Hint: Defeating the final Boss:
This Boss is only available in the full version of the game. The Boss is very large, has a large amount of firepower and can withstand a large number of hits from your best weapons. Save up the maximum amount of one of the better special weapons, such as the Star Beam 2000. Immediately destroy the turrets immediately, and try to ignore the main parts. Once the turrets are destroyed the rest of the battle become much easier.
